There's nothing we love more than a good prank, especially when that prank involves a super cute celeb like Ansel Elgort surprising one of his super fans.
Surprise! Not only is 'The Fault in Our Stars' heartthrob Ansel Egort an insanely adorable and talented actor, he can also tap dance pretty darn well, showing off his moves on 'The Tonight Show With Jimmy Fallon' last night, June 2.
