We’re not sure what’s in the air, but celebs are doing some crazy things these days.

Jason Derulo was added to the list of stars wildin’ out on Sunday after he was caught right in the middle of a nightclub brawl that stopped only after sheriff’s deputies brandished their weapons. The fight reportedly began around closing at 2:00 a.m. in West Hollywood outside Bootsy Bellows.

After a circle of men, including Derulo, continued to punch and kick each other, L.A. County sheriff’s deputies made their way to the scene. Although no shots were fired, some officers carried stun bag rifles, which deploy little bags with beads.

Check out the fight footage above. No word yet on what started it all.
