The relationship between the UFC's #1 middleweight contender Chael Sonnen and the longtime UFC middleweight champ Anderson Silva has got to be one of the most entertaining relationships in the history of MMA. Simply put, they hate each other.

To give you some background...Silva has been the champ forever. The only person to get remotely close to beating him was Sonnen...who was about a 90 seconds away from a decision win, before the champ caught Sonnen in a triangle choke. Since then, Sonnen has been relentless with his attacks on Silva...both personally and professionally. Meanwhile, the champ has remained silent through it all (mainly because he can't speak English). The two are scheduled for a rematch this June in Silva's home country of Brazil.

Recently, Sonnen gave what appeared to be a sincere, heart-felt apology to Anderson Silva. He even went as far to say that he was pulling out of their fight at UFC 147. Could it be true? Is this sudden change of heart legit? Well if you know Chael Sonnen...then you know the answer.
