The lawsuit filed by Entertainment Enterprises Ltd. - the owner of W.i.P. and Greenhouse Clubs - alleges that Chris and Drake themselves were the causes behind their entourages fighting.

According to the lawsuit, obtained by E! News they "shared a grudge against the other arising out of their romantic relationships with the same woman."

The suit adds when they "crossed paths" at the venue they "began to fight violently with each other."

The club states that while it ensured no one in was armed, both artists arrived "with their own small army of bodyguards, 'security' personnel, employees, friends and other members of their entourage, consisting of at least 15 heavily built men trained and/or experienced in hand-to-hand and weapons combat."

In the fight - thought to be over their mutual ex-girlfriend singer Rihanna - each man's entourage members "fashioned deadly weapons out of whatever materials they could find, including glasses, alcohol bottles and furniture, thereby circumventing the nightclubs' extensive efforts to ensure a safe environment."

The club is asking for multiple compensatory and punitive damages totaling $16 million.

The suit alleges that "terrorized patrons ran for cover" and that clubbers used "banquettes and tables as improvised shields. Most were unable to protect themselves."

Several patrons, including NBA star Tony Parker, were injured during the incident.

DRAKE & CHRIS BROWN'S BRAWL

Although neither Drake nor Brown has been charged criminally for anything related to the brawl, the club's suit says they "should have foreseen that their notoriety and celebrity would ensure that their acts had far-reaching and devastating effects."
