Bruce Springsteen rocks Duke-UCLA game at Madison Square Garden (PHOTO)

Those weren't boos you heard at Madison Square Garden Thursday night during the Duke-UCLA game, they were calls for Bruuuuce — as in Bruce Springsteen.

The Boss himself was spotted sitting courtside rooting for the Blue Devils with his Duke undergrad daughter Jessica while the whole place was rocking.

The Yankees cap was a nice touch.

It sure wasn't the first time the pride of New Jersey heard those calls in this venue, but even Springsteen had to be thrilled watching another Big Man, Jabari Parker lay down this monster jam.
