The 2015 MTV Movie Awards was a night of unexpected mashups. While the focus was certainly on the actors and actresses, Fetty Wap and Fall Out Boy as well as Tinashe, Ty Dolla $ign and Charli XCX put on some high energy performances.

After Fall Out Boy opened their set with “Centuries,” the New Jersey sensation joined them on stage for a dope performance of “Trap Queen.” Following their mash-up was Charli who debuted her new single “Famous.” The British crooner brought out Ty and Tinashe for a live performance of “Drop That Kitty” for the first time.
