Jason Derulo unleashed a beatdown on two men who allegedly mistook him for Usher.

Video footage, obtained by TMZ, shows the “Take You Dancing” singer attacking the men at a Las Vegas hotel after they trolled him. Derulo and one of the men were passing each other on the escalator when the guy yelled at Derulo, “Hey, Usher! F**k you, bitch!”

Derulo reacted to the Usher line by charging towards the man and punching him in the face, sending him to the floor. He also allegedly slapped the second man moments later before security scrambled to break up the fight.

Police were called to the ARIA hotel during the early hours of Tuesday morning after the scuffle.

The two victims have not pressed charges, but they have up to one year to do so. There’s also the possibility that they could file a civil suit. Derulo received a trespassing notice from ARIA, and was removed from the property.

The two men appeared to suffer some bloody facial wounds but were not hospitalized. Derulo has not addressed the incident.
