Being a rap star can occasionally be a rough business. Ja Rule found this out the hard way while performing for fans at a concert. Not sure what provoked this action, but someone decided they weren’t pleased and launched a beer can towards Ja Rule’s head. Never one to be take disrespect lightly, Ja retaliated by smacking the fan in his face. It might’ve been awhile since he’s been a worldwide star, but Ja is still from New York. His gangster is not to be tested.
