Usher and Chris Brown got into a heated argument Friday night, which apparently led to some sort of fight.
There is video footage from early Saturday morning at the Skate Rock City roller rink in Vegas, where Chris was celebrating his 34th birthday among a lot of celebrity friends including Usher.
While Usher sang to Chris earlier in the evening when everything was fine, things got ugly when eyewitnesses say Chris was attempting to talk to Teyana Taylor.
Teyana was ignoring him for some reason and it pissed Chris off. He started yelling at her and that’s when Usher intervened and tried to calm him down.
Chris wasn’t having it, cursing at Usher and Teyana, but then, mostly focusing his anger directly at Usher. Eventually, Chris told his crew they were leaving and they they left. Usher took off his skates and went after them.
Eyewitnesses say they saw Usher go behind a string of charter buses where Chris and his crew were at. A short time later, Usher emerged with what appeared to be a bloody nose.
It is unclear if he went to the hospital, or if a police report was filed.
