Kendall Jenner and Cara Delevingne went to a One Direction concert on Saturday. Based on fan footage, the supermodel pals had more fun than any other Directioner there. One concertgoer caught them dancing to 1D's 2011 breakout hit "What Makes You Beautiful." They weren't just swaying back and forth—they were jumping up and down and kicking their legs like Rockettes. So while Kendall and Cara had worn hoodies and bandanas to the show, presumably so that they wouldn't get noticed, their fangirling gave them away. Watch below.
