Nicole Richie could be set for a full-time acting career after impressing co-stars and bosses during her recent sitcom guest spot.

The reality TV star began shooting her cameo in Chuck last week - accompanied on set by baby daughter Harlow - playing the high school nemesis of regular character Sarah, played by Yvonne Strahovski.

And she is being tipped to return by sources on the show. An insider tells People.com, ?It was fantastic. She was friendly. Everybody loved her. She has a great fight scene."

The episode will air in October.
