Anna Faris has signed on to star in the CBS comedy pilot Mom from Two and a Half Men and The Big Bang Theory creator Chuck Lorre.

The actress will play a single mother who decides to turn her life around and get sober in Napa Valley. Warner Bros. Television is producing the pilot, which CBS ordered last month. The actress, best known for film roles in the Scary Movie series and The House Bunny, only has two credits on the small screen. She starred in a multi-episode arc on Friends, and played herself in HBO's Entourage.

Chuck Lorre wrote the pilot script with Two and a Half Men executive producer Eddie Gorodetsky and story editor Gemma Baker. It isn't known when production will begin on the pilot.
