Usher and Chris Brown, two prominent R&B stars, were involved in a heated argument that turned violent outside the Skate Rock City roller rink in Las Vegas, where Chris was celebrating his 34th birthday among a slew of celebrity friends, including Usher. TMZ obtained footage of the lead-up to the altercation, which occurred in the wee hours of Saturday morning.

According to eyewitnesses, Chris was attempting to talk to Teyana Taylor, who was sitting on a bench just outside of the rink, but she was ignoring him for unknown reasons. This reportedly angered Chris, who began to yell at her, prompting Usher to intervene and try to calm him down. However, Chris continued to curse at both Usher and Teyana, directing most of his anger towards Usher.

Eventually, Chris told his crew that they were leaving, and they exited the facility. Usher, who had removed his skates, followed them. An eyewitness who claims to have been present for the incident reported seeing Usher go behind a string of charter buses in the parking lot where Chris and his crew were located. Shortly thereafter, Usher emerged with what appeared to be a bloody nose. It is unclear whether he went to the hospital or if a police report was filed, as Vegas Metro has not received any reports of the incident.

Usher, Teyana, and Chris have all remained silent about the incident and have not confirmed or denied reports initially put out by Hollywood Unlocked, which first broke the news of the altercation between the two R&B stars. However, Usher is scheduled to perform at the Lovers & Friends festival in Las Vegas tonight, as is Chris. It is unclear whether either of them will follow through with their performances.

The altercation between Usher and Chris Brown is the latest in a string of high-profile celebrity feuds that have played out in public. Fans are eagerly waiting for updates on the situation and whether it will have any impact on the scheduled performances by the two stars.
