Beefing with Eminem is the best thing that's happened to Machine Gun Kelly.
Which is pretty unique as Shady used to be known as a career killer.
The Em vs. MGK beef had gone cold. But Kelly will surely provoke the Stans with this video he just posted of him performing his Eminem diss "Rap Devil" to a packed house in Detroit.
"Somebody help your mans up/ Knees weak of old age," Kelly raps, before letting the enthusiastic crowd finish the bar with a "the real Slim Shady can't stand up."
Looking back, who won the Eminem vs. MGK beef?
