Machine Gun Kelly performed his Eminem diss track, 'Rap Devil' in Detroit this weekend at The Fillmore.

This is not the first time that MGK has taken shots at Em during a Michigan concert. He did the same thing during a show in Grand Rapids last year shortly after the beef became front page news.

This is different though. . . this is Detroit.

I thought something like this wasn't supposed to happen. I mean, if MGK did get through the 'No Fly Zone' to actually perform in Detroit, how did the crowd not boo him off the stage?!

I know it's MGK's concert, and really only his fans would be there, but The Fillmore went nuts when Kelly performed the song. He put up a short clip on his IG page.

The crowd definitely was feeling Kelly during the track.

The Fillmore was at capacity for the first show of MGK's Hotel Diablo tour, and he made time to show his Michigan fans love.

I'm a little confused though . . . does this mean that the Em and MGK beef is done or is it about to get bigger?
