Having a bad day? Well that's all about to change.

If you haven't had the chance to watch Emma Stone take down Jimmy Fallon in an epic lip sync battle on "The Tonight Show," then you're seriously missing out. The famous redhead proved to be his toughest competitor as she wowed the crowd with her rendition of Blues Traveler's "Hook" followed by DJ Khaled's 2010 jam "All I Do Is Win."

Fallon put on quite the show too, as he took on Iggy Azalea's "Fancy" and Styx's hit "Mr. Roboto." But alas, Stone stood out, shocking everyone with her beyond impressive rap-lip syncing skills.
