Ever wish you could kick reality TV star Spencer Pratt's butt?

Somebody a few years back got to do just that, and it was all legal, and caught on this exclusive Breaking Celebrity News video!

On the film a winded Pratt, then 19, is getting manhandled, pinned, twisted and turned by a more experienced martial artist during the 2004 US Open Jiu-Jitsu in Santa Cruz, Calif.

And Pratt, who's married to Hills castmate Heidi Montag, remembers as if it were yesterday.

"It was my first tournament," explained Pratt, who fancies himself as a tough man. "I was a purple belt, which is the equivalent to a black belt in most martial arts. I, of course, had to go for the purple belt because I thought I was in karate kid or something."

Karate Kid? Hey, the real karate kid wins!

"I had real competition," Pratt said, "the guy that beat me was the world champion in our weight class the year before. If I had beat that guy I would have had to face Nick Diaz, strike force champion for MMR."
