Bruce Willis is a New York Jets Fan (VIDEO)

If there was any doubt whether Bruce Willis is a New York Jets fan, he set the record straight on 'The Late Show With David Letterman' (weeknights, 11:35PM ET on CBS).

Bruno burst onto the stage wearing a green and white Sanchez jersey, carrying pom poms and cheering his little heart out. "Nobody in the history of this show has ever made an entrance like that!" exclaimed Letterman. "It was fantastic!"

Yeah, maybe. And a little frightening, too. Maybe Willis is having a mini-breakdown over the fact that the Jets were eliminated from the Super Bowl last Sunday.
