In case you needed another reason to adore the very lovable Ansel Elgort, Jimmy Fallon has you covered. The Fault in Our Stars actor stopped by The Tonight Show on Monday, hitting the stage to show off his skills. Elgort is a trained dancer, and he impressed the late-night host when he busted a move on the show. After talking about his costar Shailene Woodley, who also starred alongside him in Divergent, Elgort joked about posing with posters in the subway. Watch the pair's hilarious interaction above, then then get excited for the movie to hit theaters this Friday with a look at the best snaps from the film's NYC premiere!
