Chris Brown was left bloody after a confrontation with Drake and his entourage early this morning in NYC.

TMZ has confirmed with DCPI that the two singers and their crews got into it at WIP nightclub in New York — and that 5 people were left injured from the violent outburst.

We’re told there were no critical injuries … just bumps, bruises and lacerations. No arrests were made.

There are reports that the two started throwing blows (and bottles!) over Chris’ ex girlfriend, Rihanna, who Drake is also rumored to have hooked up with … but we have not confirmed these reports.
