The 22-year-old star was there to watch the Cleveland Cavaliers facing off the Golden State Warriors at the Quicken Loans Arena during the game 3 of the NBA Finals.
Bieber was caught on camera throwing punches at a man, but his much-bigger opponent easily retaliated with his own fist and sent the star to the ground. The incident reportedly happened outside his hotel, reports aceshowbiz.com. Earlier in the day, Bieber was reportedly booed by the home team’s fans.
He was joined by his homie Lewis Hamilton at the Quicken Loans Arena, but it’s unclear if the F1 racer was present during the brawl.
