10 Biggest UFC Celebrity Fans

7. Justin Bieber

https://www.youtube.com/watch?v=FeZnne8Sfjc Canada's most infamous export stirred up some controversy last year by tweeting a request for a stream to UFC 162 just as the dramatic events of the main event were unfolding - Anderson Silva clowning, then being knocked out by challenger Chris Weidman. Bieber had upwards of 40 million twitter followers at the time. 40 million witnesses to his request for a pirated copy of the event. Oh, and the kid is estimated to be worth over 100 million dollars. Really Bieber, just order the damn thing. Doesn't your own industry continually whine about the impact of piracy? However, Dana White, always one to keep his celebrity acquaintances happy, refrained from one of his usual tirades, saying he was "friends" with Bieber when the subject came up on ESPN 2's "Highly Questionable" shortly after the event. Despite the misstep, Bieber has attended live UFC events in the past, and there's no question that he's a huge fan.
