On Tuesday night (Oct. 20), Balmain and H&M collection finally launched. While everyone was expecting a fashion show and party, they definitely were not expecting a performance from the Backstreet Boys, which is exactly what they got.

While BSB obviously have a fan in Balmain Creative Director Olivier Rousteing, there were two people in the audience who were the most excited for the performance—Gigi Hadid and Kendall Jenner, maybe you've heard of them?

Dressed in the collection outfits they walked the show in, Gigi and Kendall posted up in the front row, living out my middle school dreams. Look how into it they are—guess we finally know whether they were more into BSB or *NSYNC, eh? Sorry, Justin Timberlake.

When Nick Carter approached, they reacted appropriately, turning toward one another and freaking out. Sure, they may be two of the most in-demand models in the fashion industry right now, but when Nick Carter is singing "I Want It That Way" three feet from your face, the response is universal.

Of course, their dancing was much more graceful than, say, mine would've been, but that's not surprising—have you seen Kendall lead a dance army? Yeah.

Walking a runway and watching a Backstreet Boys show from the front row—all in a Tuesday night's work for Gigi and Kendall, HBU?
