“The Chainsmokers” crashed Huntley High School’s prom on Saturday night at the Hyatt Regency in Rosemont.

The surprise was made possible after students emailed the band knowing they were making a tour stop right across the street at the Allstate Arena.

The band coordinated the surprise visit with the high school principal.

“The Chainsmokers” posted a photo on twitter saying, “We crashed this prom just now. It was across the street from our area show, so why not.”
