Machine Gun Kelly is telling the hilarious story of a time he left his pal Pete Davidson unprepared for a high-profile party! On "The Tonight Show" on Thursday, the singer told Jimmy Fallon that he once invited Pete to join in on his Easter plans at a friend's house, and the comedian brought 40-ounce bottles of alcohol with him. MGK conveniently left out who was throwing the party: Sandra Bullock! "Pete was like, 'Why would you do this to me? We look so stupid,'" he recalled.
