Justin Beiber punched a dude in the head that was reportedly choking a girl at a Coachella after party over the weekend. The guy, who appeared to be on something, walked into the after party and went crazy and grabbed a woman by the throat and wouldn't let go.
Justin and his crew were screaming at the guy and the guy responded with "Go f*** yourself" so Bieber punched the guy in the head which freed the woman. Reports are saying that the girl was the guys ex.
Oh, and yes Justin was a Coachella over the weekend hanging out and having some fun with his friends.
