EXCLUSIVE PHOTOS - Mario Lopez Runs Around The Grove In His Underwear After Losing Super Bowl Bet

He's a man of his word!

Just before 10am on Tuesday morning, Mario Lopez sprinted around the Grove in Los Angeles in his underwear, and not only did cameras for Extra catch the whole thing, but so did we!

"Lost my Super Bowl bet on @extratv. Now I have to man up," he tweeted. "Jim Harbaugh couldn't you give it to Gore at least one time on that last drive?!" Mario was rooting for the San Francisco 49ers, and while they had an amazing comeback in the second half of the game, they ended up losing 34-31. So close! But we do love the purple manties (his own Rated M brand, natch) and Nikes, not to mention that Ravens helmet!

Back in 2008 Mario told People Magazine, “My shirtless photo-shoot days are behind me,” but just a few years after that he covered himself in gold paint and posed for his new underwear line MaLo by Mario Lopez. So what did he have to say about breaking his vow to keep covered up? "I'm selling underwear! There’s an intention there and a purpose. I've kept true to my word and I've never posed just to pose for artistic sake or whatever. And believe me, I get asked a lot."

But what does he have to say about this shirtless 40 meter dash?
