Not surprised that Chris Brown lost his temper while partying in Vegas? Well, us neither. That's what happened while the singer was at Haze at Aria the night before the Billboard Music Awards in May 2012. Breezy reportedly started fuming after the girls he was sipping champagne with moved on to the next table. "Brown approached the guys in the group [at the next table] and started getting visibly agitated. Brown stood up, and looked like he was about to start a fight when club security stopped him," an insider tells the New York Post. "He got in the guy's face and was cursing at him, and saying, 'Are these girls with you or with me?' The guy was stunned by it." Before things got too violent, security showed Chris the door. "Haze has a zero tolerance policy for violence," the club rep says.
