Justin Bieber is at it again, as the pop singer continues to be embroiled in controversy over his alleged misdeeds. This time, Bieber and his entourage are being accused of starting a brawl and leaving one fan unconscious on the pavement.

The incident started early Sunday morning when a female fan reportedly hit on Bieber while he was partying at a swanky night club in the Hamptons. After Bieber rejected her advances, a male friend of the woman's engaged Bieber in a heated exchange.

Bieber did not react calmly to the provocation. He allegedly took off his shirt and began to wildly shout and gesticulate inside the night club. His security team took the singer out into the parking lot, but the man he had been shouting at followed him out of the club. Soon enough, that man was knocked unconscious on the pavement.

"Upon his release from Peconic Bay Medical Center, the subject responded to Southampton Town Police Department...he was involved in an altercation and physically assaulted by subjects unknown to him but he believes them to be members of singer Justin Bieber's security staff who he stated were also at the night club," said a statement by Southampton police.

It is  being reported that Bieber became incensed when he saw that he had been followed out to the parking lot, and climbed through his SUV's sunroof to confront the man again. It is not believed that Bieber actually threw the punch that knocked the club-goer out, and so far he has attempted to distance himself from the rumors.

"The most recent rumors might be the funniest of all. Where do u get this stuff??? #focusedonreality," tweeted the international pop sensation.

Bieber's entourage is currently under investigation in the matter. The singer has certainly had his fair share of controversy lately. From being caught on camera urinating in a restaurant's mop bucket to racking up massive traffic ticket fines in Dubai, Bieber has been involved in numerous morally questionable incidents as of late.

"I'm not naive to think that my child is perfect and making all the best decisions of his life," said Bieber's mother Pattie Mallette. "I mean, people don't talk about all the great things he does every day. Every night before a show, he meets with Make-a-Wish kids. He goes to sick kids' hospitals. He visits with them (and) takes his time. He gives back to charities."

What do you think, is all of the good that Justin Bieber has done outweighed by his increasingly outlandish and dangerous behavior? Comment below and let us know how you feel about the pop icon.
