Twitter: @machinegunkelly Machine Gun Kelly stopped by The Jeff Show to discuss his role in the movie Nerve which comes out this weekend. He says his role is very important to the movie, and has almost been secretive up until this point.. He almost gives away some spoilers but stops himself quickly before getting himself in some trouble. There is a screening of the movie tonight in Cleveland and I cannot wait to see MGK act among some greats like Emma Roberts and Dave Franco.
