Machine Gun Kelly is taking his fight with Eminem to Shady's home soil.

MGK opened for Fall Out Boy last night in Grand Rapids, Michigan's Van Andel Arena and he had some choice words for Em.

Rap Devil 😈

This is not a battle between Michigan and Ohio. This is a battle between the past and the fucking future. Knees weak of old age — the real Slim Shady can’t stand up,” MGK said before launching into his Eminem diss “Rap Devil.” 

Earlier this week, Eminem producer Mr. Porter said Em would respond to MGK in time and his response would be powerful. (He can now incorporate something about how Kelly was opening for Fall Out Boy.)

Eminem also may have sent MGK a message yesterday when he silently played Ms. Pac Man on Instagram Live. Kelly has a Pac Man neck tattoo.
