Christina Ricci has committed to a guest-starring arc on TNT's "Saving Grace."

TNT announced on Monday (July 14) that Ricci will do a three-episode on the hit angel-talking drama playing the temporary partner to Holly Hunter's Grace Hanadarko.

The cable network's release offers few details on Ricci's character other than to say that she's a young detective who begins working with Grace when her current partner (Kenneth Johnson's Ham Dewey) takes a leave of absence.

Thanks to roles in films like "The Opposite of Sex" and "Sleepy Hollow," Ricci has made the transition for her child-acting roots to grown-up success. Ricci was most recently seen in "Speed Racer" and by a very different audience in "Black Snake Moan."

Hardly a stranger to TV stints, Ricci has had multi-episode roles on "Ally McBeal" and "Grey's Anatomy." She's also popped up on "Joey" and "Malcolm in the Middle."

"Saving Grace" airs on TNT on Monday nights at 10 p.m. ET.
