Chris Brown's Temper Gets Him Kicked Out Of Las Vegas Club: REPORT

Chris Brown finished his court-mandated anger-management classes in December 2010, but the "Turn Up the Music" singer might need a refresher course.

According to the New York Post, the 23-year-old's famous temper didn't do him any favors at a Las Vegas hot spot the night before the Billboard Music Awards.

Witnesses told the paper that Brown spent Saturday night at Haze at Aria trying to charm a group of young women and buying them multiple bottles of Champagne, but became "visibly upset" when the women moved on to the next table.

"Brown approached the guys in the group [at the next table] and started getting visibly agitated," claimed the witness. "Brown stood up, and looked like he was about to start a fight when club security stopped him."

According to the source, Brown got up in the guy's face, swore at him and demanded, "Are these girls with you or with me?" The issue didn't escalate however, as both Brown's security and the club's security swooped in to cool things down and escorted him out of the club.

A rep for the singer insists the account was "not true" but a rep for the club did, in fact, confirm there was an incident involving Brown. However, they wouldn't go into detail. "Haze has a zero tolerance policy for violence," the club's rep told the New York Post.

Brown has a reputation for having more than just a hot temper -- and has been known to turn violent at times. In 2009, he brutally assaulted then-girlfriend Rihanna, leaving her bruised and bloodied. The singer then had a complete meltdown in March 2011, when "Good Morning America" host Robin Roberts pressed the singer about the assault. Brown stormed off set into his dressing room, where he smashed a window.

The weekend was bittersweet for Brown: He picked up the Top R&B Artist award on Sunday, but his dance-heavy performance, which seemed to sacrifice any actual singing, wasn't well received by a few celebrities, who publicly bashed Brown. Singer Pink, her husband, Carey Hart, and model Chrissy Teigen each took to Twitter to call Brown out for lip-synching.
