Machine Gun Kelly found himself on the receiving end of angry boos and middle fingers from the crowd at Louder Than Life festival before seemingly getting into a fight with a concert-goer over the weekend.
A video shared by a festival attendee on YouTube shows MGK receiving jeers and boos during his set while dozens of people give him the middle finger. Another upload from a different account appears to show the rapper-turned-rocker throwing a punch at a member of the crowd who shoved him mid-performance.
US media outlets claim the boos were likely from outraged Slipknot fans attending the metal-leaning concert, after MGK and Slipknot frontman Corey Taylor entered into a war of words last week.
Warning: The below video features strong language.
The 'My Bloody Valentine' hitmaker pushed back at assertions he received a frosty reception at Louder than Life, tweeting: "I don't know why the media lies in their narrative against me all the time but all I saw was 20,000 amazing fans at the festival singing every word and 20 angry ones."
MGK included a video from a fan that showed the crowd singing along with his song and didn't feature any booing.
The 31-year-old didn't publicly respond to the footage of the physical altercation that looked to have taken place that same night after MGK came down from the stage to get close to fans, only to have a man attack him. The Billboard Music Award winner was held back by security as he attempted to retaliate.
MGK angered Slipknot fans when he called the band "old weird dudes with masks" in response to singer Corey Taylor's thinly veiled remarks about MGK in a podcast interview earlier this year.
Along with calling out the band on stage, MGK claimed Taylor had been kicked off a song from his Tickets To My Downfall album because his verse was "terrible".
Taylor responded by sharing screenshots of what he claimed were emails between him and MGK's musical collaborator Travis Barker, in which MGK raved about Taylor's work on the song only for the Slipknot singer to pull out of the project because he didn't like MGK's notes on how to finesse the verse.
Louder Than Life took place in Louisville, Kentucky and also featured Metallica, Korn, Disturbed, Judas Priest, Anthrax, Jane's Addiction, Rise Against, Cypress Hill and Suicidal Tendencies.
