Justin Bieber allegedly headbutted another man at a party last weekend and now the police are involved.

The incident happened at the Italian restaurant Serafina in LA. A staff member was supposedly taping the singer messing around with a friend when the Biebs asked him to stop.

When the guy didn’t stop Bieber allegedly lunged at him. The employee reported the incident but doesn’t want to press charges.

Regardless, the Los Angeles Sheriff Department is still investigating it as misdemeanor battery.
