Machine Gun Kelly may be finished releasing Eminem diss tracks, but he’s keeping his feud with the rapper alive.

Appearing on the Power 105.1 radio show The Breakfast Club on Thursday ahead of his new EP out Friday, MGK said he had another song aimed at Eminem ready for release but shelved it after he heard “Killshot,” Eminem’s latest diss track he released last week.

“I had a clip ready,” MGK said. “I heard ‘Killshot,’ and I put that (expletive) back in the holster.”

Why? MGK was offended by Eminem calling him a “mumble rapper,” a less-than-flattering term used to describe the younger generation of Soundcloud rappers with indecipherable  lyrics.

“It’s a six for me, dog,” MGK said, rating the song on a 10-point scale. “‘Killshot’ was a leg shot. With ‘Rap Devil,’ we’re talking about facts while you want to talk about man buns? Answer the (expletive) facts. I’m an actor, homie, how disconnected are you? You called me a mumble rapper. Let’s pour some out for this old dumbass.”

When asked if he would think about someday reconciling with Eminem, MGK wasn’t interested.

“He doesn’t want to have a conversation,” he said, before speaking directly to Eminem. “(Expletive) you. You blew it. You blew it. It’s cool ’til it ain’t. I wish he would shut the (expletive) up.”

Meanwhile, 50 Cent is not happy that “Killshot,” which was originally Eminem’s reply to Machine Gun Kelly’s own diss track “Rap Devil,” became the biggest hip-hop debut in YouTube history, racking up 38.1 million views in its first 24 hours.

In an NSFW Instagram post, 50 Cent posted a picture of a headline announcing Eminem’s “Killshot” feat, with a caption complaining about the song’s success. He even appears to suggest anyone who’s watched it shares in the blame for helping keep the feud alive.

“Man do you see this (expletive), think about it the biggest hip-hop song on YouTube,” he wrote. (For the record, “Killshot” is not YouTube’s biggest hip-hop song – it just had the streaming service’s largest 24-hour debut.)

“Now everybody gotta take a L because of MGK,” he continued in the caption. “What the (expletive), we didn’t have anything to do with this (expletive) … LOL get the strap.”

The new Instagram post suggests that 50 Cent has soured on the feud. In an NSFW post from Monday, the Eminem protégé seemed to be egging him on, telling MGK, “Oh (expletive), Boy, you (messing) with the wrong one. LOL.”

The feud, which began in 2012 when MGK called Eminem’s daughter, who was 16 at the time, “hot as (expletive),” was reignited with the Aug. 31 release of the Detroit rap veteran’s “Kamikaze” and has festered throughout September. Things went from bad to worse when Eminem released “Killshot” last week, prompting MGK to post a concert photo of what looks like a supportive crowd behind him as he flipped off the camera. He captioned the photo, “He missed.”

The concert’s attendees took to the post’s comments section to set the record straight, claiming thatMGK baited the crowd into unknowingly taking a picture that targeted Eminem.
