American singer Jason Joel Desrouleaux, better known by his stage name Jason Derulo was handcuffed after attacking two men at the lobby of a Vegas casino on Tuesday.

It was gathered that one of the men shouted ‘f–k you bitch’ at him and called him ‘Usher.’

A video shared online by @christian_labare, showed the 32-year-old singer and dancer pouncing on the hecklers at the Aria Resort and Casino while coming off an escalator and passing a group of onlookers who had taken out their phones to capture their brush with the musician on video.

Someone in the crowd was heard shouting, “Ay, why did you slap him, dawg?” and then a separate voice yells “Hey Usher, f–k you, bitch!” in an apparent reference to another recording artist, Usher.
