Oh no, he has the fever… UFC middleweight champ Anderson Silva looks to be a big Justin Bieber fan, as he performs a full set of Bieber hits with a dance squad. Not too surprised as the pound-for-pound great is known for his love of the King of Pop, Michael Jackson. Silva would put on a Michael Jackson impression in his Pride FC walk-outs. The video above is actually dated back to 2011, but it caught our attention as Anderson just tweeted to Bieber, asking his thoughts on his impression.
