Jimmy Fallon, Emma Stone in Lip-Synch Battle Featuring Songs by Iggy Azalea, DJ Khaled [VIDEO]

Actress Emma Stone knows her hip-hop. At least she does when it comes to a lip-synching competition.

On Monday night's (April 29) airing of 'The Tonight Show Starring Jimmy Fallon,' the redheaded star of 'The Amazing Spider-Man 2' gave arguably one of the best TV lip-synching performances ever, and if you missed it this is how the epic battle went down.

Fallon started things off by mouthing the lyrics to Iggy Azalea's 'Fancy,' which was pretty impressive despite the former 'Saturday Night Live' actor botching a few words. After that, Stone grabbed the mic and went right into Blues Traveler's 1994 cut 'Hook.'

Not only did she land every word precisely -- including the parts where the lyrics are delivered quickly -- her facial expressions and contrived levels of emotion fit the song perfectly. At that moment, Stone was clearly ahead in the battle.

For his second go, Fallon lip-synched the words to the 1983 tune 'Mr. Roboto,' which of course made it necessary for him to break out the robot dance, making his performance that much more comical.

However, Stone stole the show and closed out the competition by doing a seamless rendition of DJ Khaled's 'All I Do Is Win.' Between nailing the hook and Ludacris' verse, some might wonder if she practiced beforehand or if she rocks Khaled's music regularly.

Either way, the slender actress was the clear winner of the competition. Even Fallon thought so. "That was the best one that has ever been done on the show," he admitted. "Emma Stone [is] the winner right now. Clear, clear, clear winner."
