Ansel Elgort, you are such a little muffin.
Augustus Waters Elgort was cool as a cucumber, answering questions about his big-shot fashion photographer dad and secret love for ballet, among other subjects. Disappointingly, he was not asked about "TFIOS." (What gives, Kimmel?)
It was still a very wonderful interview, and you should watch in the videos above and below.
After the segment, Elgort excitedly posted screenshots from the show on Instagram to commemorate the big event.
