Johnny Knoxville is such a gallant gentleman. While out in New York City the other night with some pals and Kate Moss -- who he may or may not have had a fling with -- the married Dukes of Hazzard costar started a nasty bar brawl when another patron began to pester Miss Moss. Beer bottles were flying -- one shattered on Johnny's hand, leaving him a bloody mess -- prompting bouncers to remove everyone from the premises. Wonder what Melanie Clapp, who is Johnny's poor, poor wife, was doing while he defended the supermodel's honor. And isn't it ironic that Kate dumped Pete Doherty because he started a brawl last weekend? Hey Kate: Your "friends" can start fights but your lovers can't?
