Machine Gun Kelly more or less quit the rap game after he tried beefing with Eminem.

Now he's back in to beef with Jack Harlow, who recently declared he's the best white rapper since Shady.

MGK disputed that in a freestyle over JAY-Z's famous "Renegade" beat.

"Make sure there's no confusion / I'm a great white, I can eat their barracudas/See who I am, you're stupid/ NIce to meet you I just put this hole in the ground for you like a soccer cleat shoe/ "I see why they call you Jackman / You jack man's whole swag /Give Drake his flow back man."

Jack Harlow is having a tough run.  First, the sales for his Jackman album came in soft.  Now this aggression.

Jackman vs. MGK, who you got?
