On the night of his fight when McGregor threw a spinning roundhouse kick that blew out his knee, the Ohio native immediately mocked him while referencing one of his diss tracks saying “knees weak of old age, the real Conor can't stand up.†A day later, the rapper turned rocker took to Instagram to double down on his diss aimed at McGregor, and he's not backing down from a beef that started between them on the VMA's red carpet back in 2021.

â€I'm aware I did a post yesterday, and I should probably apologize for absolutely nothing, homie,†MGK said on Instagram. “F*ck this dude. That's how beef works. We don't like each other. Everyone's saying ‘oh you commented on his age, he's only one year older than you about his knees.' We don't age the same. My knees are awesome. ‘Oh you wouldn't say it to his face?' I already did. That's why this picture exists of this little leprechaun punching up and missing me and me not flinching.

“Where the f*ck is the rest of the footage where we toss this little guy like a piece of dirty drawers across the red carpet? That's why all the footage starts with him far away.â€

That incident got plenty of publicity with security separating MGK and McGregor during the red carpet festivities. Obviously, five years later the bad blood still exists — at least where MGK is concerned.

“Buddy, you look like a drunk, ugly extra in a Sherlock Holmes movie,†MGK said. “What in the 1934 am I looking at? Fix your face. Holy shit. Why are you kicking him when he's down? F*ck this guy when he's down, up, sideways, asleep, while I'm peeing. F*ck him.

“What in the f*ck Liddell happened to the landing strip on your head? Worst 10 seconds I've ever seen. Thanks for the walkout being longer than the fight. You wasted everyone's time. It's pissing me off.â€

McGregor announced on Monday that he's planning to have surgery on his injured knee, although he didn't specify the exact nature of his injury. As for MGK, he's now managed to get into a public beef with McGregor after also having a past altercation with reigning UFC middleweight champion Sean Strickland when they met at a Power Slap event. Here's hoping MGK can settle these beefs better than he did with Eminem.
