Ohio rapper Machine Gun Kelly isn’t slowing down his hard-hitting Slim Shady jabs. Last night, the Bad Boy Records artist continued his anti-Eminem campaign at a Michigan concert.

Opening up for rockers Fall Out Boy at Grand Rapids’ Van Andel Arenas, MGK told Marshall Mathers’ local fans the rap battle is far from over.

“This is not a battle between Michigan and Ohio,” the Cleveland-based Machine Gun Kelly told the Grand Rapids crowd. “This is a battle between the past and the (expletive) future.” “Knees weak of old age — the real Slim Shady can’t stand up,” MGK continued, as he launched into a live version of “Rap Devil,” his harsh lyrical attack on the veteran Detroit rapper.

In a recent interview, West Coast rapper O.T Genasis said Em shouldn’t entertain MGK’s disses.

“Stop the white on white crime, man. [laughs] Let’s stop the white on white crime. I actually didn’t hear [MGK’s ‘Rap Devil’] – I heard a snippet of it. I haven’t heard it. I heard Em went after him. I’m not sure. I heard Em went after him and then now he’s just trying to hold down his part. You kinda can’t just sit there and be a b*tch and let somebody talk about you. Em is the greatest. Yeah, the greatest. The goat. [Should Em respond?] Nah. He’s too great for that. Too great for that.” (TMZ)

Producer Mr. Porter believes Em is going to inevitably respond to MGK’s verbal shots.

“Right now, he in there working. We doing something else right now, but trust me, we’ll get to it. I’ll tell you this: I wouldn’t wanna be him. It’s great that you took that opportunity and did that, hey, kudos to you, good for you. The one thing that I’m worried about – you remember when [Marvel Cinematic Universe character] Thanos threw that whole planet at Iron Man?” (Skoglund16 TV)

This week, D12’s Bizarre weighed-in on MGK blasting away at Em with his “Rap Devil” diss song and warned him about what’s to come.

“Yo, everybody keeps hitting me up, asking me if I’ve heard the Machine Gun Kelly diss. Yes, I’ve heard it. I think it was good. I think this is the best I’ve ever heard Mr. Kelly rap in his life. I think he stayed up all night. Wrote the best possible bars he could possibly could and I think it’s good for hip-hop. But boy, but boy, the repercussions. Ohhh. Ohhhhhhh. Ohhhhh. The boy gonna do you something nasty. Y’all better stop playing with that boy.”
