Machine Gun Kelly certainly displayed his "Wild Boy" persona last night on his Raging With Reindeer II Tour. Before he even began his set at The Queens Hotel in Nanaimo, B.C., the 23-year-old rapper from Cleveland got into an altercation with a security guard on stage. It's unclear from the video what the exact cause was, but MGK took matters into his own hands by headbutting said security guard before the rapper's team stepped in to stop it from getting out of hand. The unexpected act brought cheers from his fans. Machine Gun Kelly would go on to finish his 90-minute set without any further issues from venue security.
