Singer Jason DeRulo was reportedly involved in a bar fight, while he was out partying late on Saturday night, with police having to intervene and end the brawl.

TMZ.com reports that while it’s unclear what started the fight, Jason had jumped into a crowd of men that were brawling at the nightclub Bootsy Bellows in West Hollywood, at around 2 am. One of the men was on the ground, being punched and kicked by the others. The fight only ended when armed LA County sheriff’s deputies came in and cleared up the area.
