Kevin Connolly and Chad Muska Fight over Nicky Hilton

A word to the wise: Watch what you say about Nicky Hilton while her beau, the usually laid-back Entourage star Kevin Connolly, is in the vicinity. At the West Hollywood hot spot Hyde on July 27, pro skateboarder Chad Muska was guest-DJ-ing, and he made a lewd comment about Hilton (22) a witness said.

“Kevin jumped on the DJ booth and hit Chad,” the witness recalls. “Chad tried to hit him back, but at that point they were separated [by security].” After Muska was escorted out the front door, another witness says Connolly (32) “went back to his seat and continued to chat with Nicky.”

Word is Muska was completely wasted that night, and couldn’t fight back. Must make Connolly feel pretty tough. Security called police once Muska was outside claiming Muska hit one of them first, then roughed him up, but Muska was too wasted to hit anything. Oh well, Muska still got what he deserved for being such a butt head while inebriated.

Connolly’s rep had no comment. Muska couldn’t be reached.
