Ansel Elgort is a modern-day Renaissance man. A skilled actor (you can see him next in Baby Driver) and devoted Knicks fan, Elgort is a fellow of many interests. When he's not creating sexy music videos with his girlfriend, he's covering musical hits and sharing them on Instagram. Case in point: on Tuesday, he posted a video of himself playing the piano and singing to "City of Stars" from La La Land. He's no Ryan Gosling, but he definitely does the song justice.
