August Alsina hit the stage for a good cause at the Chaifetz Arena in St. Louis, on Saturday night, but unfortunately things got a bit ugly behind-the-scenes.

The New Orleans singer was tapped to perform at the State Of Emergency 2 concert, with a portion of the proceeds going to the Put down the Pistol program, but his crew got into a messy altercation with one of the show's promoters backstage.

TMZ has obtained footage of the incident, and they claim that two separate fights took place: One in the singer's dressing room, and another in a hallway backstage.

In one video we can see members of Alsina's crew fighting with a promoter who has been identified as LooseCannon S.L.I.M., and in a second clip we see him get caught up in the mix, although it's unclear if he was fighting or just trying to break things up.

It's also unclear what triggered the fight, with one report claiming that it was due to Alsina being late, and another because he was upset about having to perform before Migos.

MTV News has reached out to August Alsina's label, but Def Jam had no comment as of press time.

Following the incident, LooseCannon S.L.I.M. hit Instagram to reveal that he'd emerged from the fight without any damage. So much for keeping the peace.
