Eminem dropped his surprise album Music To Be Murdered By last week, where he took aim at several rappers including Machine Gun Kelly - but MGK says he's been "rich and mad" for two decades.
"But when they ask me is the war finished with MGK? Of course it is / I cleansed him of his mortal sins, I'm God, I'm the Lord, forgives even the devil worshippers /I'm moving on but you know your scruples are gone when you're born with Lucifer's horns," Em raps on single "Unaccomodating," which features Young M.A.
When MGK caught wind of the track, he hopped on Twitter, calling Em's offering, "bullsh*t."
He tweeted, "mad af I just stepped out a loud room to hear this bullsh*t."
He followed up the tweet with, "he's been rich and mad for 20 years straight."
The pair exchanged diss tracks back in 2018. Since then, it's been fairly quiet until Em's recent release.
