Chris Brown seen arguing with Usher

In a video obtained by TMZ, the “Under the Influence” crooner could be seen allegedly arguing with Teyana Taylor at the Skate Rock City roller rink in Las Vegas during his 34th birthday party Friday. Usher is then seen trying to talk to Brown, who began cursing while skating away. According to the outlet, Brown allegedly got upset when Taylor, 32, was ignoring him while he was trying to talk to her at the party. The “Go Crazy” singer allegedly “started to yell at her” and that’s when Usher intervened. TMZ claims that Brown “wasn’t having it” and began cursing at both Taylor and the “Let It Burn” singer, 44, before leaving the skating rink with his crew. Usher allegedly took off his skates to go find Brown and an eyewitness told TMZ that they saw him go behind a string of charter buses in the parking lot, where the birthday boy and his crew allegedly were. The witness told the outlet that “a short time later” they allegedly saw Usher emerge with what appeared to be a bloody nose.
