Nicole Richie Returns to 'Chuck!'

Nicole Richie is returning this fall to kick some serious arse on NBC's hit series, Chuck. Richie, 28, will reprise her role as Heather Chandler—an old high school nemesis of Sarah’s (Yvonne Strahovski) in an October episode.

Richie's character, Heather was originally introduced on the show two years ago when she guest starred as a butt-kicking villain and all-around badass. Back then, Richie described her character as “kind of that b----y mean girl.”

Heather returns to Chuck and Sarah’s lives just as the couple is having some serious problems in their relationship, and she’ll use those problems to her advantage. Don’t remember Nicole on Chuck? Check out her introduction to the series below:
