50 Cent gets stick over new movie role

Rex Features

50 Cent has been mocked by friends after being told that he must slim down for his role in forthcoming movie Streets of Blood.

The US rapper, who will play a policeman in the movie, has been instructed to prepare for filming by starting a new aerobic exercise fitness programme.

"To lose some of 50 Cent's hard-earned muscle his trainer has incorporated aerobic routines into his training schedule," a source told The Sun. "But he is getting a lot of grief from his mates."

Val Kilmer, Dylan McDermott, Sharon Stone and Brian Presley will also star in the movie.
