Hellraising In The Hamptons? Justin Bieber At It Again, Instigates Bloody Brawl

Justin Bieber instigated a bloody brawl in The Hamptons this past weekend, according to insiders, and we've got all the details of the skirmish right here on RadarOnline.com.

The Baby singer, the NY Daily News Confidential column reported, was at Southampton's South Pointe nightclub 2 a.m. Saturday, and settled into the club's VIP area flanked by four guards onlookers described to the paper as “intimidating," "overbearing,” and "heavy-handed in their protection of" the Biebs.

When a woman tried to talk to the cocky Canadian singer, her male friend exchanged heated words with Justin, at which point Bieber "ripped his shirt off and went nuts.

"He was screaming," an onlooker said, after which the singer was whisked away to an SUV in the parking lot. Despite Bieber leaving, his pals and security continued to scrap with the clubgoers, leading to blood being shed, insiders said.

It's the latest incident in a string of them, in which the once fresh-faced singer has acted out with bad behavior that could be described as bratty as best, and in the process, has called the singer's long-term career viability into serious question.
