Machine Gun Kelly Slates Slipknot At Riot Fest

It's beef!

Machine Gun Kelly slated Slipknot onstage at Riot Fest over the weekend.

Slipknot's Corey Taylor criticised the singer during an interview earlier this year, doubting his credentials as a rock artist.

He said Machine Gun Kelly aimed to “take something that’s been around forever and then just basically rework it and call it new – even though it’s completely derivative”.

Machine Gun Kelly hit back onstage at Riot Fest in Chicago, sharing a bill with Slipknot.

He told the crowd: “You wanna know what I’m really happy that I’m not doing? Being 50 years old wearing a f***ing weird mask on a f***ing stage!”
