The 31-year-old musician reemerged for the first time since getting physical with a concertgoer over the weekend, taking to his Instagram and posting a video showing him bleeding profusely from the nose.
In the footage, Fox's rocker beau seems to be enjoying trolling his fans as he's seen practically licking up the blood from his leaky nostril.
Wearing a red hoodie pulled over his head, MGK took his phone and flipped it to capture the oozing mess on film.
Sharing a close-up of his face, the Bloody Valentine singer can be seen with blood trickling from his nose down to his mouth. He appears to be trolling haters, who were fired up after he unloaded on a fan at the Louder Than Life Festival in Louisville, Kentucky, on Saturday.
MGK was having a tough night pre-fight. The festival audience didn't take kindly to the musician, who recently dissed shock rock legends Slipknot.
In a video of his set, the crowd can be heard booing and seen flipping Fox's boyfriend the bird.
Things went from nasty to worse when one crowd member decided to push the singer. MGK retaliated by reportedly throwing a punch. It's unclear if he made contact.
This isn't the first time Fox's man has gotten physical in the last month.
Weeks ago, MGK got into a heated brawl with MMA fighter Conor McGregor at the VMAs. Unlike this weekend's festival fight, Fox was smack dab in the middle of the altercation.
As Radar reported, the Transformers actress was rushed to safety by security when their confrontation almost turned physical.
