The 2014 MTV Movie Awards are live this Sunday from L.A.’s Nokia Theatre and the network has a monster performance in store. Before they embark on their "Monster Tour" this summer, Em and Rihanna will join forces at the Theatre for their first performance of their smash single “The Monster."

Originally released on Em’s Marshall Mathers 2 LP in November, “The Monster” reached number one on the Billboard Hot 100 chart and has stayed in heavy rotation on airwaves across the world. Following the MTV Movie Awards, the two will begin preparing for their joint tour which kicks off Thursday, August 7 at the Rose Bowl in Pasadena, CA. -Peter Walsh
