At a DVD launch for Lillo Brancato Jr's new movie "Back in the Day," writer and producer William DeMeo found himself jailed after getting into a fist fight with the manager of Lounge Beautique. It was also a birthday bash for Demeo.

The trouble started when Demeo left the club to walk a friend to his car and would be right back. Demeo returned and the manager of the mid-town club would not allow him to re-enter. Demeo told the NY Post "I couldn't believe it. It was my party and the guy was giving people a hard time all night long. He bumped into me and that's when I lost my cool."

Bouncer Chronicle spies said Demeo delivered a solid left to the manager's jaw, knocking out one of his teeth. Attending the party were former NY Yankees David Wells, David Cone, private eye Bo Dietl, Savion Glover, hip hop legend Melie Mel, DJ Kool Here and porn stars Heather Pink and Gia Jordon.
