Diddy hasn't given up on that acting career.  After appearing in Showtime's  small screen adaptation of the famed play "A Raisin in the Sun," Variety reports Sean Combs  is jumping on board the latest Judd Apatow-produced comedy, "Get Him to the Greek" starring Jonah Hill and Russell Brand.  The picture follows a record company intern (Hill) who is put in charge with transporting an uncooperative rock legend (Brand) back to Los Angeles for a comeback concert.  Diddy will play a record company executive. 

"Mad Men's" Elizabeth Moss and "Adam's" Rose Byrne have also joined the cast as the respective love interests of both Hill and Brand's characters.
