Elisabeth Moss and Diddy Go 'Greek' for New Movie | Sean P. Diddy Combs
Mad Men's Elisabeth Moss is temporarily leaving the Sterling Cooper ad agency in N.Y.C. to join Sean "Diddy" Combs in the spin-off to the comedy Forgetting Sarah Marshall.

The actress, 26, and Diddy will star alongside Jonah Hill and Russell Brand in the upcoming Judd Apatow film Get Him to the Greek.

In the film, Moss will play Daphne Binks, the girlfriend of Hill's character (Aaron Greenberg), who gets tempted by an out-of-control, self destructive rockstar (Aldous Snow) played by Brand. Combs plays the role of "Sergio," the owner of the record label. The film follows Greenberg who's hired by a record company to accompany Snow from London to a concert at the Greek Theatre.

Moss, who got engaged to SNL's Fred Armisen in January, plans to film the movie at the same time as Mad Men.
