We already knew that Justin Bieber was a fan of mixed martial arts, as he's been seen at several UFCs. What most folks didn't know was that he is not only a fan, he's a fighter. And he just might be the next big thing in MMA.
Complex Magazine profiled Bieber for an upcoming issue in an article entitled: Justin Bieber: Second Round Knockout. Their website, Complex.com, included some pics of Bieber in MMA action. He looks great and armbars and much bigger opponent, but if he wants to get into the UFC, he'll need to bulk up some to make the lightest weight division, which is 125 pounds.
