Justin Bieber is once again on the wrong side of the law. Media reports claim he reportedly headbutted another guest at a pre-Grammy party last weekend.

It all went down at Serafina, a restaurant in LA, at 2AM. Justin was there because his producer friend was throwing a party.

Justin was supposedly joking around with Disney actor Kyle Massey when a staffer started taking video. Bieber asked the staffer to delete the recording and then they started arguing. That’s when Justin lunged at the guy, according to eyewitnesses.
