50 Cent gets grief from mates after taking up aerobics

50 cent is getting grief from his mates after taking up aerobics to slim down for his latest movie role.

50, real name Curtis James Jackson, plays a cop in Hurricane Katrina action flick Streets Of Blood — and the muscle-bound rapper has been told he needs to slim down before filming starts shortly.

50, who launched his acting career with 2005 film Get Rich or Die Tryin’, will co-star with Val Kilmer and Sharon Stone.

A source said: “To lose some of 50 Cent’s hard-earned muscle his trainer has incorporated aerobic routines into his training schedule.

“But he is getting a lot of grief from his mates.”
