One of the features of The Tonight Show is the amazing dance battle.
This week's show saw Blake Lively appear as a guest and of course she triumphed in the battle.
Blake and host Jimmy Fallon took turns to make up random dances on the spot like the "Ballerina Who Keeps Dropping Marbles" and "The Catching The Bouquet."
The best part came at the end however, when they both danced to the "Riverdancing Frankenstein."
