When it came to partnering with Coty to create the ultimate perfume, Roberto Cavalli was primed for the challenge.

“I was waiting a long time to have such a special fragrance,” he told PEOPLE recently. “I spent a lot of time to create something that I really like.”

Sitting low in his chair, and surrounded by lanky employees with thick Italian accents, the storied designer detailed whittling the scent down to three key ingredients. “At the beginning they gave me a lot of small bottles and I didn’t know which one to choose because one was too sweet and the other one was too …” he trailed off. Clearly, creating a fragrance is hard work.

Comprised of a trifecta of harmonious scents — orange flower, roasted Tonka bean and peppercorn for a spicy note — the eponymous scent was created as a tongue-in-cheek homage to the designer’s late mother.

“She adored perfume,” he said, his eyes glassing over with remembrance. “She used to buy the most horrible, cheap perfume. It was strong, strong perfume. I like mine because it is soft, delicate … not too much.”

So when asked which of his A-list fans would best embody his “sexy, feminine, aggressive” scent, Cavalli was quick to choose Jennifer Lopez. “It’s for a woman full of energy,” he mused. “I can see Jennifer singing and dancing with my perfume. I would love that.”

Arriving at QVC’s runway show in New York Wednesday night, Camila Alves seemed to have a little extra sparkle, in the form of a stunning three-stone sparkler on her finger. The handbag designer was out for the first time since her Christmas engagement to longtime love Matthew McConaughey, and put her gorgeous engagement ring on display for all to see.

“I am really enjoying being engaged right now … no wedding plans as of yet,” she told reporters. But speaking to PEOPLE earlier in the week, she was happy to dish on her fiancé’s sense of style. “Matthew has great taste,” she said. “He always has great opinions on what works and what doesn’t.” He even gives input on Alves’s handbag line, Muxo, which she designs with her mother. “We are one big family so we share everything — including opinions on the creations for the line.”

Alves’s latest collection, which she’ll present on QVC this Saturday, was inspired by her recent travels through Texas, Arkansas, New Orleans, California and New York. “We are really having fun mixing all of the inspirations from the various landscapes that we’ve been collecting for some time now,” she shared.

The Brazilian beauty fell in love with fashion at an early age; her mother, a designer by trade, would let her help with various projects. “It taught me so much about design,” she explained. “And after I had moved to the States I was looking for something to do with my mom to help the family in Brazil … so we created our first handbag together.”

Though the pair has their moments — “Sometimes we butt heads like any mother and daughter,” Alves admitted — they feel “blessed” to work together. “We have a great relationship, and we create in a very unique way together.”

Catch Alves on QVC Saturday, selling the latest from Muxo (including her favorite, a leather satchel with a kiss-lock front pocket, right), plus sales from Geren Ford’s Geren Lockhart, Dennis Basso, Mark Zunino and Lori Goldstein (10 p.m. EST). And tune in Friday (10 p.m. EST) for launches from Christina Ehrlich, Isaac Mizrahi, Fern Mallis, Karen Zambos, Marc Bouwer and Cynthia Vincent.

SHOP STAR LOOKS FOR LESS

If Minka Kelly was nervous about walking in Wednesday’s Heart Truth Red Dress Show at New York Fashion Week, she definitely wasn’t showing it. The actress hit the runway in a glimmering, custom creation by Diane von Furstenberg, and was met with cheers from the adoring crowd.

Kelly got involved with the annual show through sponsor Diet Coke, once the company asked her to be their celebrity ambassador. “Before I got involved I didn’t know that heart disease was the number-one killer of women,” she told PEOPLE exclusively (hear more in the clip above). “If I get one girl to go to the gym one day more often than she does … then I’ve done a good job.”

Joining Kelly on the catwalk were stars like Christie Brinkley (in Pamella Roland), Jenna Elfman (in Alberta Ferretti), Rebecca Romijn (in Marchesa), Rose McGowan (in Donna Karan) and Elisabeth Röhm (in Nicole Miller). “I’m excited for Chaka Khan and I’m excited for Gloria Estefan,” Kelly revealed before the show. “I’m such a huge fan of both of them, so I’m so honored to be in their company.”

The scene backstage was lots of fun: the seventh floor of New York’s Hammerstein Ballroom was transformed into a giant salon, with hair stylists from Elizabeth Arden’s Red Door Spa, makeup artists from Bobbi Brown and nail guru Deborah Lippmann running between celebrities to primp and perfect. (Check out our Pinterest page for some behind-the-scenes photos.)

The Red Dress Show — now in its 10th year — raises awareness about heart disease and the Red Dress, unveiled by the National Heart, Lung and Blood Institute in 2002 as a symbol for the cause. For more information on prevention, and the campaign, visit hearttruth.gov.

And to help in the fight, pick up a four-pack of Diane von Furstenberg’s limited edition Diet Coke bottles ($30), sold throughout the month of February; 100 percent of proceeds will benefit the Foundation for the National Institutes of Health.

IT’S NEW YORK FASHION WEEK! GET ALL THE LATEST HERE

Wednesday marked the beginning of New York Fashion Week, but last week, one of the city’s biggest fashionistas was already out and about. Speaking to PEOPLE Thursday at Godiva’s 2012 Valentine’s Day event at the Andaz 5th Avenue in New York, Blake Lively showed off a stunning Valentino ensemble, pairing the chic getup with — you guessed it — Christian Louboutin shoes.

The Gossip Girl star is known for her love of Louboutins — the designer even helps her decide which of his shoes to wear sometimes — but her latest interaction with him really takes their relationship to a new level. “My gosh, [the spring collection] was sent to my house today, and they’re so beautiful,” she revealed. “They’re amazing. I walked around my apartment wearing them.”

Her favorites? “These cage, crystal-encrusted shoes and one with a feather detail coming off of it.”

Lively, who doesn’t have a stylist, described her style muses as “women from times past: Katharine Hepburn, Audrey Hepburn, Grace Kelly. I love the sophistication. I love every single detail.” Sounds like she’d love to live among them, too. “I would love if I could wear little cut-off gloves every day,” she mused. “That would make me so happy. I’d go to a grocery store in a beautiful hat with lace dripping over the eye.”

But her handbag would certainly be current. “I do love my Chanel bags,” she said. “They come with me everywhere. That’s the truth.”

Best known for her spitfire sense of humor and otherworldly good looks, Olivia Wilde’s stay-gorgeous routine is surprisingly girl-next-door.

“[I wash] and moisturize my face with drugstore brands like Cetaphil and CeraVe,” she tells PEOPLE.

And when that newly lopped do becomes a hassle, the TRON star looks to easy solutions. “I’m into cool stretchy headbands,” she says. “I throw it up and try to make it look interesting and put on a headband and then it looks like it was all intentional.”

While her beauty basics are decidedly simple, Wilde’s fitness routine runs the gamut from the serious to the silly. “I need kind of Ashtanga, like good, serious yoga,” she explains. “I never feel more beautiful than after I’ve really spent some time breathing.”

But when downward dog isn’t cutting it: “Hula hooping is one of those things that everybody sort of scoffs at,” she adds semi-seriously, “but I know people who have lost serious weight hula hooping.”

She’s taken two nights off from new mommyhood this week to support hubby Jay-Z, but Beyoncé needn’t look further than her fingernails to be reminded of the new girl running the world these days: daughter Blue Ivy Carter.

“You see the blue nails. You see the IV tattoo on her finger. It’s clear that she was bringing Blue along with her because she doesn’t want to be away from her for a second,” Beyoncé’s longtime manicurist, Lisa Logan, tells PEOPLE of her Monday manicure.

Logan, who painted the singer’s fingernails with Nails Inc.’s new “Baker Street” polish (the star accented the look with a two-finger ring by Bing Bang for WeSC), says the whole experience felt serendipitous. “I don’t roll with less than 200 bottles of polish on any given day,” she explains. “When I pulled all of my colors out, [Baker Street] and two other colors were sitting at the top of the pile, and [Beyoncé] said, ‘I want this!’ She didn’t even look or blink at the other colors. She was like, ‘Oh no, I want this,’” Logan recalls. “Ironically, when I came in, the first thing she asked me for was Minx. I always have Minx nails, [but] this was the one day I didn’t have them on me!”

So how is the newly manicured mom adjusting to motherhood? “Amazingly,” Logan says. “When I see her, I’m like, ‘Girl, you’re glowing.’ She’s so elated. Motherhood is written all over her face. She’s owning it and wearing it well.”

There’s no limit to the number of charities celebrities seem to support, but at the moment, many are taking a stand for OrphanAid Africa, a charity championed by Rachel Roy. The designer recently created a handbag — the Rachel Roy OrphanAid Ghana clutch — designed to raise awareness about the non-profit and honor the West African nation at the same time.

“Clutches are one of my favorite shapes of handbags to carry, and when I work on product to sell for charities I want to create something that is refined, effortless and beautiful to look at … like the children that inspired the effort,” she explains to PEOPLE.

The colors in the bag — which retails for $49 — are taken from the country’s flag and washed “for a softer effect,” Roy explains. “The fabric is natural and raw; love the balance of the two.”

Hilary Swank (above) and AnnaLynne McCord have both been spotted carrying the clutch in recent weeks, with many stars sure to follow suit. One hundred perfect of net profits from sales will benefit OrphanAid, which helps Ghana’s orphans through programs in care reform, education and development. Grab the bag now on rachelroy.com.

“It’s so hard to find sexy intimates at an affordable price,” Sofia Vergara laments to PEOPLE. “All women should be able to get beautiful, comfortable intimates.” Thankfully, now they can: the actress is adding sexy, lacey bras and panties to her successful Sofia by Sofia Vergara line at Kmart. Problem solved!

The star’s intimates line includes three bras and three panties in a mix of red, purple, pink, black and animal print. “Honestly I love the entire collection,” she shares. “But if I had to pick a favorite … it would be the animal-print bra because I love prints, even underneath my outfits.”

Vergara thinks sexy undergarments “set the tone” for the rest of a woman’s outfit; therefore, they should always be special. “I think every woman should start by putting on a beautiful bra and panty,” she shares. “It doesn’t even have to be lingerie.”

And for those who wonder if the line is sexy enough, Vergara promises her Modern Family character, Gloria Delgado-Pritchett, would approve. “She would love these,” she says. “All the colors and cuts make all different types of bodies look great.”

The bras and panties range from $10-$15 and will hit Kmart stores and Kmart.com in late February. Perhaps Vergara will even give boyfriend Nick Loeb a sneak preview on Feb. 14, too. “I like the classic Valentine’s Day things like flowers, dinner, maybe a movie,” she reveals. “But I like to be surprised, so hopefully he’ll come up with something fun!”

New mom. Same old irrepressible glamour.

Beyoncé gave birth to her daughter Blue Ivy only a month ago. But in her first two nights out on the town, she’s picked up right where she left off — as one of the world’s most gorgeous and stylish women.

On Monday, she turned heads at husband Jay-Z’s Carnegie Hall concert in a hip-hugging Alice by Temperley dress and a pair of Christian Louboutins. Then on Tuesday, for Jay’s encore show, she sported a sexy, skintight black sequin cocktail dress by Monique Lhuillier.

She looked ravishing in both dresses. But tell us, which was your favorite look?

You’ve had him in bed — and now you can play with him in the pool. Eddie Cibrian is stripping down (again!) for Charisma, modeling the brand’s soft towels in the sexy spring 2012 ads, shot at a private residence in Los Angeles.

Though Cibrian — divorced from Real Housewives of Beverly Hills star Brandi Glanville and now married to country singer LeAnn Rimes — knows lots of ladies enjoy looking at his shirtless pictures, he seems to keep the modeling job in perspective.

“You have a lot of people on the photo shoot looking at you, going, ‘Oh that looks wonderful, that’s unbelievable … those [towels] look great,’” he told PEOPLE in September. “I realized it was all about the product, and not about me.”

Still, Cibrian — who appears in the upcoming Tyler Perry film Good Deeds – makes it hard to focus on those towels when he looks so good drying off with them!

Model Chrissy Teigen has had more than her share of painful razor cuts. “I go very fast, I’m often shaving on the go,” she tells PEOPLE. “I shave twice a day — I have dark hair, I have to — and I’m doing it so often that I want to feel smooth, not dry.”

Though she’s been guilty of using men’s razors — stealing her dad’s blades when she was younger, and swiping fiancé John Legend‘s Gillettes from time to time — the Sports Illustrated stunner is now enjoying smoother, softer shaves thanks to the new Venus & Olay razor, the official razor of SI‘s upcoming Swimsuit Issue.

“It’s the first beauty partnership for SI,” Teigen explains. “We’re constantly thrown different beauty products and things people want us to take photos with, but it’s not fun unless it’s something you really believe in.” As part of the partnership, Teigen will star in upcoming beauty-related websiodes on si.com in conjunction with the Swimsuit Issue’s release.

Needless to say, Teigen’s now addicted to the two-in-one razors, which feature five blades and a moisturizing shave gel bar. (The products will hit drugstores in March, and range in price from $9-$19.) “I was going to wear this long, Gothic-y black dress to the Grammys this weekend,” Teigen says, “but now I’m making it a specific point to get my smooth, soft goddess legs on the red carpet.”

As an honorary Venus “goddess,” Teigen joins the ranks of Jennifer Lopez, who famously flaunted her gams for the brand, too. “She’s so gorgeous, so to even be in the company of her is just ridiculous,” Teigen says. “Who would be better?”

So, with her new partnership in the news and SI‘s swimsuit edition on the way (it hits stands Feb. 14), can Teigen tell us anything about the ever-popular issue? “I would be screaming it all from the rooftops if I could,” she says, genuinely. “I will say I’m very excited for it to come out.”

She’s sampled chili, pancakes and a whole lot of steak on this season’s Top Chef, but Padma Lakshmi is miraculously avoiding weight gain and breakouts. How? By boxing. “A poet introduced me to it,” she tells PEOPLE of the sport, which she’s practiced for 10 years. “I just found it was a great workout, very gratifying.”

Lakshmi — who hits the gym two to three times per week with a trainer, and uses the speed bag, jumps rope and does calisthenics — credits boxing with her trim figure, as well as her glowing skin. “I think that sweating a lot and getting your circulation going influences your skin a lot, and helps everything rejuvenate itself,” she shares. (Regular facials, some Shiseido foaming face wash and a light moisturizer help, too.)

The former model showcases that skin — and her best boxing form — in Danskin’s “Move for Change” campaign, which also features Hilary Duff, Jenny McCarthy and Christie Brinkley. “The photo shoot was great,” she says. “It turned out to be a fun day.”

Lakshmi’s involvement with Danskin benefits her charity of choice as well; the company makes regular donations to the Endometriosis Foundation of America, a cause close to her heart. And that symbiotic relationship makes the star even happier. As she says, “It was a really great opportunity to partner with a brand that I’ve always loved, while raising awareness about my foundation at the same time.”

CHECK OUT THE STARS’ BEST WINTER WORKOUT LOOKS

With those sculpted limbs, an army of LBDs and gleaming locks, Jennifer Aniston is timeless — and logic defying.

“I don’t feel my age,” she says in the March issue of InStyle. “I feel young every day. It’s in the spirit.”

Crediting cardio, a balanced diet and an arsenal of must-have products for her looks, the Wanderlust star confesses she is a creature of habit. “On the red carpet, it’s time for me to start doing something different,” she says. “I play it very safe because I just want to be comfortable … if I could wear a jersey tank that went down to the floor, I would.”

The natural brunette is also considering ditching the golden hue that has become her trademark. “I’ve been thinking about dyeing my hair a dark brown,” she says. “I feel it would be healthier.”

But while she approaches beauty with a seasoned pragmatism, Aniston says boyfriend Justin Theroux‘s convictions do not affect her own. ”He has great style,” she confesses. “It’s very specific, and it has been his style forever. Has it influenced mine? No, but I know people say it has.” To read more on Aniston’s fashion philosophy, pick up the March issue of InStyle, on stands Feb. 10.

She may be in the midst of an Oscar campaign, but in Boy. by Band of Outsiders’ newest Polaroid campaign, Michelle Williams looks ready to quit her day job.

It’s her second turn modeling for the brand, and this time around, the My Week with Marilyn star plays an unruly office assistant: pulling pranks, filing reports and halfheartedly performing due diligence before taking a lunch break.

Despite the shoot’s location — a Hollywood cemetery! — Williams happily hams it up it in the brand’s floral spring/summer collection.

It seems designer Scott Sternberg has a knack for taking stars out of their natural habitat: previous campaigns depict Kirsten Dunst as a zookeeper, James Marsden as a mailman and Rupert Grint as a hard-partying gambler. Tell us: What do you think of Williams’s cool campaign photos?

It’s officially a trend! Rachel McAdams is the latest star to add bangs to her hairstyle, debuting the look at the Los Angeles premiere of The Vow (sponsored by Ralph Lauren Romance) Monday night. The star stepped out in a sky-blue Vivienne Westwood dress and glimmering jewels, complementing her look with smoky eyes, red lips and her new blonde bangs.

McAdams joins a growing list of leading ladies who’ve added bangs to their hair recently, including Jessica Biel, Rose Byrne, Cameron Diaz (sometimes), Olivia Wilde, Kim Kardashian (who tried clip-ons) and Reese Witherspoon, who cut them to cover a forehead scar. Kelly Clarkson rocked them during the Super Bowl, and Sarah Michelle Gellar added a few face-framing bangs recently, as well.

We think McAdams always looks lovely, but want to hear your thoughts.

With her hair constantly at the mercy of curling irons, straighteners and blow dryers, Nicole Scherzinger relies on hydrating products to keep her hair healthy. And now, she’ll likely have a lot of them at her disposable: the singer and former X Factor judge is the newest face of Herbal Essences.

“It’s amazing,” she tells PEOPLE of the new gig. “I have a big grin on my face and I’m glowing. I’m really proud to be partnered with this brand.”

Courtesy Herbal Essences

Though Scherzinger calls her “super-long” hair “strong,” she says it’s often hard to take care of because it is subjected to so much heat styling. “I always have to change hairstyles, whether it’s being on TV one minute to being on stage the next, then going to dinner or a meeting,” she explains. “It’s important to keep it hydrated, and use the right products to protect it from the heat.” To that end, she credits Herbal Essences’ Hello Hydration, Hydralicious and Long Term Relationship with locking in moisture and preventing split ends.

When she’s enjoying a day off, Scherzinger generally gives her hair a break, letting it air dry before tossing it up in a bun. But she’s no styling amateur herself: the day of her Herbal Essences shoot, the singer was even giving her glam squad advice. “I know all the mousses, honey,” she shares. “Normally people associate mousse with perms, but with this hair, are you kidding me?! Mousse equals volumizing.”

Scherzinger will appear in Herbal Essences’ print ads as well as commercials — some of which will feature her music. “It’s what I’ve worked so hard for my whole life,” she says. “Not only to have music as my driving force, but to build my brand and be associated with products I believe in — those that are a direct reflection of who I am.”

TRY ON THE LATEST STAR HAIRSTYLES IN OUR ‘INSTANT MAKEOVER’

She recently headlined a Duran Duran music video and still gets booked to walk the most coveted runways, but Naomi Campbell says there’s nothing ‘super’ about her storied career.

“I would never call myself that,” she says of the term ‘supermodel’ in the March issue of Harper’s Bazaar. “I don’t have any superhuman powers.”

To that end, the 41-year-old works hard to maintain her famous figure. “For me, carbs are a treat now,” she says, admitting to doing “everything I can to keep my skin elasticated.” (While speaking with Oprah Winfrey in 2010 she confessed to going on 18-day cleanses and jumping rope to keep her face lean.)

“I still love what I do,” she explains, but instead of ‘supermodel,’ she’s drawn to terms including “transformation, reinvention, and chameleon,” buzz words which demonstrate a marked departure from her mantra in the late ’90′s. “I never diet. I smoke. I drink now and then. I never work out. I work very hard and I am worth every cent,” she infamously told Playboy in 1999.

It wasn’t just about planking; Katy Perry‘s recent stint as a mermaid had to do with her latest series of ads for haircare line ghd. The singer channels Little Mermaid Ariel in her new U.K.-only campaign, (ironically) advertising a hair dryer from below sea level.

“I love it because I’m such a fan of the Disney movies,” the newly single star says of her campaign, shot by David LaChapelle. “Ariel is such a big influence. It’s always fun to dress up once in your lifetime as a mermaid and have that fish fin tail.”

The glimmering “tail” Perry wears in the photos was custom-made by a Dubai-based designer, but the singer’s favorite part of the look seemed to be wearing the lavender wig. “It was fun,” the blue-haired star shares. “It’s as if Lisa Frank had done The Little Mermaid.”

So should we expect to see Perry — who explored past decades in her last round of ads — donning a mermaid costume on her next tour? “I would wear it again,” she says. “I actually thought about wearing it for Halloween.” Tell us: What do you think of Perry’s aquatic ad?

Back in December, Rachel Zoe was unusually tightlipped about expanding her fashion empire.

But now that she is unveiling a costume jewelry range ($195-$695, to be sold exclusively at Bergdorf Goodman and Neiman Marcus) and cold weather accessories, she can’t help but gush about the new endeavors.

“I’m a hand-talker, so that’s what this is about,” she tells WWD of an Art Deco-inspired collection of rings, cuffs and necklaces adorned with tassels and knotted accents.

The higher price point reflects a conscious expansion for Zoe, who previously found remarkable success in affordable fashion. “I’m someone who looks at my brand holistically,” she explains. “I go to style my show and I’m like, ‘I want hats. I want gloves. I want all these things. Okay, wait, I’m a designer now, so let’s do it,’” she says of the second category, which will offer cashmere-lined scarves, leather gloves and some faux, some real, fur pieces ($95-$1,500).

And though The Rachel Zoe Project has yet to be renewed for a fifth season, the stylist remains unflapped: “It’s been four seasons, it’s in 20 countries. Businessmen watch it, bankers, I get a lot of hits from a lot of different demos. So do I need it? I don’t know. After four years, maybe there’s something to be said for starting something new.”
