VIDEO OF MIKE TYSON TRAINING JUSTIN BIEBER IN VEGAS

Mike Tyson tweeted a video Monday that shows him training Justin Bieber last weekend in Tyson's garage.

Tyson is heard complimenting the kid for his boxing skills. The video was taken when Bieber was in town for Billboard Music Awards.

Based on how slick he looks on the bag, Bieber has clearly got the boxing bug. Earlier this month he hung out with Floyd Mayweather Jr. and carried his championship belts into the ring.
