Ansel Elgort really knows how to "Shake It Off."
While chatting with Clevver News, the cast of "Insurgent" was asked to sing a Taylor Swift lyric. Theo James had some major struggles, Shailene Woodley basically made up an entirely new song -- but we got it, it was kind of like "You Belong With Me" -- and as it turns out, Elgort is a Swift expert.
With true grace, he rattled off an entire, super-complicated line from "Shake It Off."
Get it, Ansel.
