A representative for Chris Brown has hit back at a $15 million lawsuit over his infamous June brawl with rapper Drake, branding it "frivolous".

The two stars' entourages clashed during a night out at New York's W.i.P. club and the donnybrook is believed to have erupted after the rival artists exchanged words over Rihanna, who was romantically linked to Drake following her 2009 split from Brown.

Bottles were smashed during the fight, while basketball ace Tony Parker was among the clubgoers injured in the bedlam, and executives at Entertainment Enterprises, Ltd., the company which owns the Manhattan hotspot, placed the blame on Drake and Brown in legal papers.

They claim the embattled musicians "shared a grudge against the other arising out of their romantic relationships with the same woman" - but Brown's spokesperson is unimpressed with the legal action.

TMZ.com editors claim a representative for Brown told them the star's lawyer Mark Geragos said, "It's a frivolous lawsuit."
