Ice Cube has defended his decision to take on police officer roles in Hollywood.

The rapper turned actor - whose 1988 track 'F**k Tha Police' with N.W.A sparked controversy on release - insists he doesn't ''have a problem'' playing an officer on the big screen since the movie industry is ''obsessed'' with cop stories.

Ice Cube - real name is O'Shea Jackson - told Collider.com: ''Hollywood is obsessed with police stories. If you're an actor in Hollywood and been doing it over 25 years, like myself, it's going to happen. As long as it's acting, I don't have a problem. I become a real cop, then give me a call.''

Although the 44-year-old star has played a number of on-screen law enforcers, he admitted to being ''blown away'' by the success of his latest movie 'Ride Along' - in which is plays the hot-tempered officer James Payton - when it crossed the $100 million barrier at the US Box Office.

Ice Cube said: ''At the time it had crossed that number, I kind of knew that the momentum would take it over that. We were just blown away by the first weekend, having that number. A number in the forties when predictions were high twenties for some people. That number right there is the number that really kind of had me on cloud nine the most.''
