Nicole Richie, mother of a five-month-old baby and designer of a line of jewelry, got a guest starring role on the famous NBC comedy “Chuck.”

The former “Simple Life” star will play the role of Special Agent Sarah Walker’s archenemy. They haven’t seen each other for ten years, since they finished high school, and are about to meet at the reunion all former students will attend.

Nicole will play a "snarky and spiteful girl" and, according to executive producer Josh Schwartz, "this role is a great opportunity for her to show off her comedic skills and be diabolically evil and kick some butt. t's going to be really fun."

Nicole is thought to easily walk into the character’s shoes because she impressed at the audition for the part and also because it isn’t the first time she proves the public her acting talent.

In the past years, she appeared in other TV shows as a guest star, for instance "8 Simple Rules … for Dating My Teenage Daughter" and "American Dreams." In addition to this, she managed to have her own reality show, co-starring with her renowned friend, Paris Hilton.

Sometime in the past, E! Network said in a statement: "The Simple Life has been a wonderful addition to the E! Schedule for two years and we will always be grateful to Paris and Nicole for their hard work and graciousness."

Despite all the publicity the two starlets received lately, the show’s ratings dropped low enough and, as a consequence, E! Network cancelled Paris and Nicole's former hit show.
