Just when it seemed like Machine Gun Kelly had retreated back into the shadows — or wherever he went after his final scene in Bird Box — the self-proclaimed “rap devil” has returned to shake things up before the year comes to a close.

On Sunday (December 30), MGK hopped on Instagram and took aim at Eminem once again with a clip of his Slim Shady diss track, “Rap Devil.” 

“just to piss y’all off one more time before the year’s over,” he begins in the caption. “y’all still BIG mad. fuck rap god. i’m the rap devil. goodbye 2018.”

The back-and-forth between Em and MGK kicked off on August 31 when Shady surprised his fans with his tenth studio album, Kamikaze. The Detroit-bred Hip Hop Goliath sent a few shots MGK’s way on the track “Not Alike.” Subsequently, MGK fired back with “Rap Devil” and it was game on.

After contemplating his next move, Em ultimately decided to return fire with “Killshot,” bringing the war of words to a close.

“Killshot” marked YouTube’s biggest Hip Hop video debut in the platform’s history. Since its September release, the video has racked up over 215 million views and counting.
