Machine Gun Kelly Fans Shut Down Ohio Mall When Rapper Shows Up (Video)

Bad Boy Records' newest signee, Machine Gun Kelly, has quite a fanbase, especially in his homestate of Ohio.

Following his recently signed major label deal with Bad Boy, MGK stays connected with his fans by staging an unplanned appearance at the South Park Mall in Strongsville, Ohio ... when he tweeted (@MachineGunKelly), over the weekend, that he'd be there.

Next thing you know, it was a flash mob ... and security had to shut things down the shopping mall after a mob of fans got waaayyy too crazy, trying to touch the young rapper.

Check the video, it was chaos.
