Justin Bieber Investigated for Headbutting

Bieber BUSTED for allegedly “headbutting” someone at a pre-GRAMMYs party in LA.

The mischievous Justin Bieber was messing around with some friends at a restaurant on Saturday evening when he spotted an employee filming him. We all know how the Biebs feels about photos and paparazzi and stuff, so he reacted accordingly.

Bieber approached the employee and asked him to stop filming. He then asked that the video and any pictures of him be deleted from the employee’s phone. When the employee refused, Bieber took the next logical course of action and headbutted- wait, what?

Yes.  Justin Bieber allegedly lunged at the filmer, headbutted him and then left.

TMZ says it was a fellow employee, not directly involved in the altercatin, who called the police. It was NOT the victim. The person involved does not want to press any charges but since the police are now involved, the Biebs could be involved in a misdemeanor battery investigation.

Justin had already left the scene by the time the cops showed up. His reps have yet to comment on the incident.
