The 'Bitch I'm Paid' singer was said to be partying at Haze at Azria on Saturday night, before he was escorted out when he became "agitated" and aggressive after failing to impress a group of girls.
The New York Post reports that Brown became "visibly upset" when a group of girls for whom he had purchased bottles of champagne moved on to the next table, leaving him behind.
"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," a witness told the publication.
"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. Things were close to getting extremely ugly. Then Chris's security and club security escorted him out."
While a rep for Brown insisted that the story was "not true", a rep for Haze at Azria confirmed that there was indeed an incident involving the artist, saying simply: "Haze has a zero tolerance policy for violence."
Brown was sentenced to 180 days of community labour and a mandatory anger management class after beating ex-girlfriend Rihanna in 2009.
