Watch Ansel Elgort Tap-Dance His Way Into Your Heart

Is he Elgort or is he dancer?

This is how your little crush on Ansel Elgort suddenly explodes into double-extra-super-strength levels of swoon.

The actor made his first ever appearance on "The Tonight Show" on Monday, where he chatted with Jimmy Fallon about the weird new world of mega-fame that he's entered ever since being cast in "The Fault in Our Stars," plus dished on his friendship with Shailene Woodley, and made a full confession as to his secret love of tap-dancing. And did we get a demonstration of said dancing? Why, yes. Yes, we did.

And so, we fell in love with Ansel the way Ansel tap-dances on Fallon: very quickly, and with rather a lot of flailing.
