Yep. “He smacked the shit out of him” one witness stated.
It seems that a barista at the West Hollywood Starbucks refused to serve Justin Bieber whilst without a shirt. Justin allegedly freaked out on the guy and threatened the barista with the wrath of his bodyguard. Blake Griffin of the L.A. Clippers apparently witnessed the altercation and attempted to intervene. Yells and pushes were exchanged, then Blake Griffin smacked Bieber so hard that he knocked him to the floor. Bieber was gone by the time the police had arrived at the scene.
