Kendall Jenner And Gigi Hadid Really Like The Backstreet Boys

Last night, everyone who was anyone attended the NYC launch of Balmain x H&M. It was the be all, end all of post-Fashion Week events that simply could not be missed. Balmain It-Girls Kendall Jenner, Gigi Hadid, Jourdan Dunn, Bella Hadid and Karlie Kloss walked the runway, making every piece seem even more stunning in person than the original look book. 

We heard that there would be an epic dance-off at the event, but nothing could have prepared us for the Backstreet Boys closing the show with a surprise performance. Everyone totally lost their $#!t—including Kendall and Gigi. Not only was it cute, but it reminded us that these model besties are products of the '90s. (We would totally freak the f*ck out of we were front row for the Backstreet Boys, too.)
