“24″ star Kiefer Sutherland headbutts a man after being interrupted during a conversation with actress Brooke Shields.

According to the New York Daily News, the man on the receiving side of Sutherland’s forehead was Proenza Schouler women’s wear designer Jack McCollough -  a close friend of Brooke Shields.

McCollough  reportedly told the authorities that Sutherland “was drunk and obnoxious and wouldn’t back down or be logical,” and that the actor “pulled this stupid wrestling move like a teenager” before the headbutt.
