Last night’s Balmain x H&M show started with a troupe of dancers twerking and voguing up and down a lit-up staircase, and ended with a performance by the Backstreet Boys. In between was, of course, the runway show, with Kendall Jenner leading the “Balmain Army” of models like Gigi Hadid, Karlie Kloss, Jourdan Dunn, and Jessica Stam. On the sidelines, Balmain-clad celebs bobbed their heads to ‘90s throwbacks like Notorious B.I.G. and the Cardigans, then rushed the stage for songs like “Larger Than Life.” Click through the slideshow to see everyone who turned out, including Kylie Jenner, Alexa Chung, Zachary Quinto, Diane Kruger, and many, many more.
