Machine Gun Kelly OUT OF CONTROL: Megan Fox's fiancé gets hysterical in the middle of a concert and ends up with a bloody face

Machine Gun Kelly lost his cool in the middle of his sold-out concert at Madison Square Garden on Tuesday. He was caught yelling at a crew member and breaking a guitar.
The Bloody Valentine singer left the stage near the end of his show in New York City and walked toward an employee. Another crew member restrained the 32-year-old singer as he screamed.
Meanwhile, his band continued to play for the crowd as MGK returned to the stage, picked up a guitar and smashed it.
After the concert, he smashed a champagne glass against his head. The glass shattered and left him bleeding during the fan-filled evening.
