Katie Holmes kept a low profile yesterday in the audience of the MTV Movie Awards. She was along to watch her husband Tom Cruise take the stage as his alter ego Les Grossman in a hilarious dance performance with Jennifer Lopez and present the Best Movie award alongside his Knight and Day costar Cameron Diaz. Tom and Katie recently performed a duet of their own, and now he's apparently all about showing off his moves. Tom revealed last night that Katie was a big fan of his spin with J Lo, saying, "She loved it! She was there while we were working on it. . . I can dance a bit. My wife's a dancer, so I like dancing." Katie popped backstage to congratulate Tom and stopped to pose for a photo with two female fans.
