Mike Tyson shows The Biebs how to box real 'pretty'

Coincidence? Just days before Justin Bieber's alleged altercation with a paparazzo, the teen singer got boxing tips from former heavyweight champion Mike Tyson. Tyson tweeted a YouTube video showing him "training" Bieber on the heavy bag. "Justin swung by my place during the weekend of the Billboard Music Awards to say hi to the family," Tyson wrote in the video's caption. "We took him straight to garage and had him hit the bags. JB's got the moves!" In the clip, Tyson encourages his pugilistic protégé: "JB ... get pretty on it, baby." Sounds like that paparazzo may have been lucky to escape with his ears intact.
