Justin Bieber: world-dominating megastar, frequent apologiser and...street fighter?

The popstar got himself into a scrap after a night at the NBA finals in Cleveland, where he retaliated to being grabbed by the neck by throwing a punch at a guy considerably larger than him. The unidentified man didn't take well to that, and the pair started scuffling before the singer was thrown into a glass door and ended up on the concrete. Footage of the fight was obtained by TMZ, they said was taken at 11pm just outside Bieber's hotel in downtown Cleveland. https://www.youtube.com/watch?v=r-4oGYvlyaM Onlookers unsuccessfully try to break up the confrontation, the cause of which still remains shrouded in mystery. Although TMZ has reported that he was being swarmed for pictures and autographs at the time, which is known to be something that irritates him. Biebs was snapped at the NBA Finals earlier in the night, where the Cleveland Cavaliers took on the Golden State Warriors in Game 3. https://twitter.com/NBA/status/740685970740289536?ref_src=twsrc%5Etfw https://www.instagram.com/p/BGavEMDxh8W/ He was wearing a Cavaliers top when the fight broke out several hours later, so maybe it was a case of some post-game taunting that got out of hand. We may never know exactly what happened, but for all you Beliebers (we know you're out there) concerned for the wellbeing of their beloved popstar, he tweeted this earlier today. https://twitter.com/justinbieber/status/741154847945265152 Looks like he emerged from battle relatively unscathed.
