A video has surfaced online and shows that things did not go well for Machine Gun Kelly at Saturday's Louder Than Life festival.
In the video, the crowd is booing and flipping off MGK, most likely due to his recent remarks about Slipknot's Corey Taylor.
"I see you dude, I see you mad as f**k in your weird f**king outfit," he told one heckler.
The woman who posted the video confirms that the heckler was her nephew, posting "THATS MY NEPHEW YOU ARE YELLING AT. watch your tone @machinegunkelly & that “weird outfit” he is wearing IS F**KING @slipknot"
