Justin Bieber got into a fight with an unidentified man outside a hotel in downtown Cleveland June 8. A bystander inside the hotel whipped out his cell phone and filmed part of the incident (video below).
According to TMZ, Bieber was in Cleveland for Game 3 of the NBA Finals and wore a Cavaliers shirt, but it's not clear if the fight was over the game. The gossip site notes that Bieber also got requests for selfie pictures, which might have triggered the altercation.
When the video begins, Bieber pushes the man, who pushes him back. Bieber throws a punch, and the man comes right back at him, eventually dragging the pop singer down onto the ground. Several people join in as the video comes to an end.
TMZ notes that Bieber "ended up on the bottom of the pile."
The man filming the video is heard saying, "S---, I'm gonna get on TMZ."
Bieber didn't get a warm welcome earlier in the night during the game at Quicken Loans Arena.
Michael Lee, a writer for Yahoo! Sports, tweeted: "Justin Bieber, supporting the home team in his Cavs T-shirt, nearly had his eardrums booed off by Cleveland fans."
Earlier this year, Bieber was in a social media feud with UFC fighter Nate Diaz.
According to Yahoo! Sports, Bieber praised fighter Conor McGregor on Instagram as a "true champion [that] fights with style and finesse" and added that Diaz's style was "terrible."
Bieber made his observations after Diaz defeated McGregor at UFC 196.
Diaz replied on Instagram to Bieber: "Shut your [expletive] a-- up."
Diaz went on to tell Rolling Stone: "Bieber don't watch the sport; he don't know the sport. I've seen a couple other people too, Drake, all these other guys that are stating their opinion."
"How are you going to state your opinion when you don't know [expletive]? You're just showing your lack of knowledge on the sport," Diaz added.
In March, Diaz posted a picture of himself with Bieber on Instagram with the caption: "All good doe."
