Beyonce the Producer

Along with being a singer, actress, and dancer, Beyonce Knowles is adding "executive producer" to her resume. Billboard reports that the 10-time Grammy winner has signed on to executive produce and star in Darnell Martin's Cadillac Records for Sony BMG Films.

Knowles will play Etta James in the period film about the Chicago record company, Chess Records; its founder, Leonard Chess; and the turbulent lives of some of the label's legends.

The cast will include actors Adrien Brody, Jeffrey Wright, Cedric the Entertainer and Columbus Short. Emmanuelle Chriqui and Tammy Blanchard co-star.

Music for the film is being produced by Steve Jordan. Knowles will record four songs for the soundtrack, which will be released through Music World Entertainment and Columbia Records.

Beyonce is even going as far as to donate a portion of her fees for the film to recovering addicts, through her family's charity, the Survivor Foundation, according to her reps.
