American R&B singer certainly knows much more than music after a video circulating online shows him knocking two men down in a fight at a nightclub.
According to a video posted by TMZ, Jason Derulo started the fight with the men because they mistook him for an usher.
The incident happened at a nightclub at Aria Hotel in Las Vegas. The Las Vegas Metropolitan Police were called at about 2 a.m, but Jason was not arrested and the victims did not press for charges.
The singer was subsequently escorted out of the premises by the resort’s security.
