Former Simple Life star Nicole Richie, 26, will expand her presence on the small screen this fall, when she appears in an episode of the NBC comedy Chuck, the network announced exclusively to PEOPLE. And Richie will be playing a role all too familiar in Young Hollywood: the Mean Girl.

According to NBC, Richie will play a “snarky and spiteful girl who tortured” actress Yvonne Strahovski’s character in high school. In the episode, airing sometime this fall, Strahovski’s character, Special Agent Sarah Walker, “must face her fears when she is forced to attend her 10-year high school reunion,” for a mission with costar Zachary Levi (Chuck) as her date.

Chuck’s executive producer Josh Schwartz says, “Nicole auditioned for the part and was very funny. This role is a great opportunity for her to show off her comedic skills and be diabolically evil and kick some butt. It’s going to be really fun.”

Richie has also guest-starred on 8 Simple Rules … for Dating My Teenage Daughter and American Dreams. — David Caplan
