Why didn’t celebrities do this stuff when I was in high school!? Recently, Kylie Jenner showed up to a prom unannounced. This past Saturday, The Chainsmokers surprised the students of Huntley High School near Chicago and gave a 10-minute performance. The students & teachers posted pics with the guys & their performance. Alex & Andrew also posted a pic with the entire school behind them. “Crashed this prom just now. It was across the street from our arena show, so why not :),” they tweeted. The Chainsmokers performed later in the evening a scheduled concert at Allstate Arena. The Hyatt in question is actually about 2.5 miles away and across several streets, as well as a highway, but hey, they were certainly in the neighborhood. While it was a surprise to most participants, the Chainsmokers’ prom appearance was actually planned, with the help of school principal Scott Rowe. “They just kind of came from backstage and just started performing ‘Closer.’ The kids weren’t exactly sure what was going on,” he told the Chicago Daily Herald. “About three words in, somebody screamed ‘That’s The Chainsmokers!’ and they just bum-rushed the stage. It says a lot about those guys and how cool they are to their fans.” Rowe told the newspaper that two weeks ago, he got a “random phone call” from a filmographer who worked for the duo, who told him, “This is going to be the strangest call you’ve ever received, but one of your students actually sent an email to the manager of the band.” “It was probably the toughest secret I’ve ever kept, because I knew the kids were going to go crazy for it,” Rowe said. “Your prom could be next,” The Chainsmokers tweeted. Not only did The Chainsmokers show up, but King & Queen were siblings!
