So many celebrity guest appearances on the horizon! First Mary-Kate Olsen steps into Samantha Who, and now Nicole Richie (never one to be out-shined) has been slated to guest star on 'Chuck'. Who will she play? In the spirit of her ole' pal Paris, she'll take on the role of a mean girl, playing a "snarky and spiteful girl" who "tortured" Special Agent Sarah Walker (Yvonne Strahovski) during adolescence. The executive producer behind Chuck talked about her appearance, saying "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." Fun! [People]
