Police in Fargo, N.D., arrested Cisco Adler, best known for that picture of him naked except for tube socks, and for his romantic relationships with various celebrities, on Thursday morning after he punched a bar employee in the nose.

The incident took place during a brawl after his band's show at The Hub.

Authorities were called to the Fargo venue about 12:24 a.m. after receiving a report of 15 people brawling and fighting security and management on the northeast corner of the building, according to local police dispatch logs.

Cisco Adler was arrested on suspicion of simple assault and booked into Cass County Jail. There were no problems with the arrest, Claus said, adding the employee made a citizen’s arrest (!?) before police even arrived.

Cisco Adler was released from jail at 1:26 a.m. after posting $500 bail.

Adler is the former frontman of the band Whitestarr, which he left in 2008. He and his new band, Shwayze, had a minor hit this year with "Buzzin'," which was featured on an episode Gossip Girl. But mostly he's known for his giant balls.

Shwayze was performing last night before the fight broke out.

The son of music producer Lou Adler, the Cisco kid has had relationships with various celebrities, including Mischa Barton, Kimberly Stewart, Lauren Conrad and Paris Hilton, according to his Wikipedia page, which he totally must have written.
