Chuck is about to welcome a brand new guest star, Nicole Richie!! From reality show lead to sitcom guest, Nicole is expanding her resume. For her short stint on Chuck, Miss Richie will be playing a 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.

That sounds pretty funny actually! Chuck’s executive producer Josh Schwartz says Nicole auditioned for the part and was really funny.

“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.”

I missed my High School reunion because I gave birth to my daughter the day before. I was SO UPSET about missing it, but obviously had a great excuse! Did any readers have to deal with a situation like the above at their reunion?
