During an appearance on The Tonight Show on Monday, Emma Stone hit the stage alongside Jimmy Fallon to join him for one seriously epic lip-sync battle. For the latest round, Fallon sang "Fancy" by Iggy Azalea and "Mr. Roboto" by Styx, while Stone — Fallon's first female contender — brought it home with very passionate renditions of "Hook" by Blues Traveler and "All I Do Is Win" by DJ Khaled. In the past, Fallon has gone up against celebrities like Joseph Gordon-Levitt and Paul Rudd, who both gave the host a run for his money, and Stone was definitely no exception, thanks to her rap talents and those priceless facial expressions.
