Fans of "The Tonight Show" are no stranger to lip sync battles between host Jimmy Fallon and his guests.
However, Emma Stone's appearance on Monday's show may have been the best battle yet.
While most of his guests stick to fairly easy songs, Stone, star of the upcoming "Spider-Man" film, didn't hold back. In fact, after her first lip sync to Blues Travelers, Fallon actually looked a little nervous.
Fallon picked it up for his second song, but then Stone dropped it on him.
Emma - 1, Jimmy - 0. Can't wait for the rematch.
