R&B singer Alicia Keys is so worried about being stalked by a crazed fan, she is considering buying herself a gun.

The 26-year-old used a firearm on the set of her new film Smokin' Aces, and now feels having access to a gun could prove useful.

She says, "I've never owned a gun but I'm seriously considering owning one now. I don't think it's necessary, but God forbid, if anything happened, I'd be prepared."

Smokin' Aces is Keys' first movie role. She plays assassin Georgia Sykes, starring alongside Ben Affleck, Ray Liotta, Andy Garcia and Jeremy Piven.
