Chris Brown and his company allegedly fought Usher at his 34th birthday hosted at a Las Vegas skate rink, and the conflict was allegedly over Teyana Taylor ignoring the birthday boy.

On May 6, at the Skate Rock City roller rink early in the morning, footage obtained by TMZ and initially broke on Hollywood Unlock depicted a heated fight between the two R&B superstars, whom sources say were close friends.

The fight stemmed from an unknown standoff between Brown and Taylor, who attended the singer’s birthday party but, for some reason, was distant from him. When the problematic artist received the cold shoulder, sources said the bad-tampered singer threw a fit, yelling at Taylor, sitting on a bench just outside the roller rink.

When Usher, who is ten years older than his counterpart, saw a berated Taylor and tried to intervene to diffuse the situation. His involvement only made Brown more upset, TMZ reported. The 34-year-old father of three cursed both of them out.

Brown told his crew that he was leaving the Skate Rock City party, and they promptly departed from the building. Usher, who he and his crew sang for Brown before the incident, removed his skates and trailed behind him.

Sources who attended the Skate Rock City party told TMZ they saw Usher walk behind a row of charter buses parked in the lot where Brown and his crew were. 

Whatever happened between Usher and Brown must have been physical because the sources say the older R&B star emerged with a bloody nose, but it is uncertain if Usher went to the hospital or filed a police report. 

The singers are supposed to perform tonight at his Lovers & Friends Festival in Las Vegas.

Neither Usher, Brown, nor Taylor have denied the allegations. It is also unclear if the men will share the stage together after their rumored fight.
