Machine Gun Kelly was previously in the news after MMA fighter Conor McGregor tried to fight the artist while on the MTV VMA red carpet. Since then, MGK has been trying to transition into the world of rock music, with the artist landing a spot on the Louder Than Life Festival in Louisville, Kentucky. However, it seems the crowd wasn’t here for MGK’s music, as people in the crowd could be seen flipping off the rapper and booing him.

While the booing and taunting seem out of left field, MGK recently trashed rock group Slipknot, saying he was happy to not be a 50-year-old wearing a mask while playing music. Take a look at the footage above.
