innocent girl caught in the middle when DRAKE and CHRIS BROWN turned a nightclub into a war-zone (PHOTOS)

Hip-hop rivals Chris Brown and Drake turned a New York City nightclub into a war zone that sent four innocent bystanders to the hospital early Thursday when they started a brutal brawl over the pop music diva Rihanna.

 One of the club-goers caught in the middle was Hollie C, an Australian tourist who was rushed to Bellevue Hospital after she was smashed in the head with a flying bottle during the fight.

 A gruesome photo shows a gash in her head and her face covered with blood. She needed 16 stitches to close the wound. 

Witnesses say the two recording stars started fighting after Chris Brown sent Drake a bottle of Champagne as a peace offering. Drake reportedly sent the bottle back with a note: 'I'm f****** the love of your life, deal with it.'
