R&B Star’s ANTI-VIOLENCE Concert Ends In VIOLENCE

R&B star August Alsina got into a brawl during a concert to promote nonviolence..

The show, dubbed “State Of Emergency,” went down Saturday night at Chaifetz Arena in St. Louis. Proceeds from the show went to the Put Down the Pistol program.

According to sources, Alsina got into it backstage with the show’s promoter, Loose Cannon Slim, after Slim got upset at Alsina for showing up late. Words were exchanged and it seemed as if it would stop there … until the punches started flying. The video is crazy — you can see Alsina go after Slim, who got knocked to the ground. One of Alsina’s people quickly pulled him off … while Fabolous watched from a distance — holding his drink. h/t tmz

No cops were called. Video.
