Kendall Jenner, Gigi Hadid Own Balmain X H&M Runway, Popular '90s Boy Band Closes Show With Surprise Performance (PHOTOS)

Kendall Jenner and Gigi Hadid might as well just do every runway show ever from now on, because these two cannot be stopped. No matter what designer they're wearing, they steal the show. They do look particularly good in Balmain, though, so it's no surprise the designer, Olivier Rousteing, brought them on to front his newest collection for H&M. 

Jenner, 19, Hadid, 20, and several other successful and gorgeous models, including Gigi's sister Bella, Karlie Kloss, Joan Small, Alessandra Ambrosio, and Jourdan Dunn, owned the runway at Tuesday night's official launch event, the Balmain for H&M Runway Show on Wall Street in New York, according to New York Magazine. This group of models is one only Rousteing could get together, and his retro vision was brought to life in the most perfect way with this underground subway-themed show.

There were his signature black, white, silver and gold embellished jackets, dresses and blazers, and too many look-completing belts to count. There were thigh-high black boots, and several bandeaus. Even the models couldn't wait to get their hands on these clothes. "It's a good feeling," Rousteing said. "When you see 40 models saying, 'I want that.'"

"I think the concept for H&M x Balmain is putting the couture in the stores," Rousteing told Yahoo! Style. "It's a really rich and strong collection that is infused with the Balmain DNA. It's richness and French, and it's inspired by pop culture and the glamour that Balmain is known for...while keeping the quality of course!"

His "Balmain Army," as he likes to call it, was beyond perfect, and this show was proof that Balmain is slowly but surely taking over the fashion world. As if these A-list models weren't enough for one show to handle, there were even more famous faces, including Kylie Jenner, Elie Goulding, Diane Kruger and Alexa Chung, sitting front row, according to The Huffington Post. Almost too much to handle, right? That's where you're wrong, because Backstreet Boys closed out the show with a surprise performance of and made basically every '90s girl's dreams come true.

Steal these looks for yourself when the line hits select H&M stores on Nov. 5.
