Machine Gun Kelly performed at Louder Than Life festival over the weekend and during his set on Saturday night received an earful of boos and taunts from those in attendance.

The culmination of which was a group of fans rushing the stage and confronting Kelly with their fists.

We don't know whether these fans were pissed of MGK stans or pissed off Slipknot fans, but either way, Machine Gun Kelly has found himself at the knuckle end of a fist more than once in recent weeks.
