Machine Gun Kelly was ready to throw punches when a straight rando came on stage while MGK was speaking at the Cleveland Public Auditorium on Tuesday, October 10. [Go to the 10:40 mark]

"My man, get the f*ck away from me," MGK told the guy. "Yo, what are you doing? This is a bad look. Don’t make me do this."

The "Rap Devil"rhymer eventually apologized for reacting the way he did, although many would probably say it was justified.

"I'm sorry, I try to live the dichotomy more on this side than the other guy," he told the interviewer. "I left that guy in the past.  I’m really sorry. I do apologize for my primal reaction."

One of the last rappers to deal with a stage crasher is 50 Cent.
