Eminem hit his old friend Machine Gun Kelly with some subliminal wordplay on his new tracks "Gnat" and "Zeus"

"They come at me with machine guns / Like trying to fight off a gnat," Shady rapped on "Gnat."

"Fair weather, wishy-washy / She thinks Machine washed me / Swear to God, man, her favorite rapper wish he’d crossed me," he went on "Zeus."

Machine Gun Kelly had two Tweets to respond to the two subliminal barbs.

"I'm under your skin.  Those subliminals," MGK typed, with appropriate emojis.

Kelly has admitted that Eminem killed his rap career when they beefed in 18.

However, his genre change from Hip Hop to Pop/Punk has been a huge success and now he's dating Megan Fox.
