Ansel Elgort Sings 'Officer Krupke' From 'West Side Story' - Watch!

Ansel Elgort suited up sharp for his appearance on The Late Show with Stephen Colbert in New York City on Tuesday night (September 10).

The 25-year-old actor opened up about getting cast as Tony in West Side Story, and revealed that when he was 12, he starred in the musical during theater camp.

“I went to theatre camp for seven years,” Ansel shared before Stephen shared images of him from the production.

It’s then that Ansel recreates the scene he was performing – and sung “Officer Krupke”!

He’s also pictured below leaving Good Morning America earlier in the week.
