Kendall Jenner, Gigi Hadid And The Backstreet Boys Star In Balmain x H&M's Runway Show

And all the models were there, obv.

Clearly, Balmain's Olivier Rousteing knows how to create some hype.

The 30-year-old designer has been expertly teasing the French fashion house's collaboration with fast fashion retailer, H&M, for the past few months, causing fashionistas everywhere (including ourselves) to anxiously wait in anticipation for the collection to drop November 5.

His latest move? A star-studded runway show, which was held on Wall Street in New York City Tuesday evening.

Naturally, the #BalmainArmy was there, with the ad campaign's stars, Kendall Jenner, Gigi Hadid and Joan Smalls storming the runway in embellished jackets, dresses and more Balmain x H&M goodness.

Joining them were Bella Hadid, Jourdan Dunn, Karlie Kloss and Alessandra Ambrosio (to name a few), all showcasing the 109-piece collection.

But aside from the impressive model roster and celebs in attendance (Kylie Jenner, Coco Rocha, Diane Kruger, Ellie Goulding and more), the evening included some very special guests for its musical performance: The Backstreet Boys.

Opening with "Backstreet's Back," the '90s boy band were welcomed by a cheering audience, dancing Olivier and models included. Brian Littrell even directly serenaded Gigi and Kendall, making all of our fashion and '90s dreams come true at once.

We have officially entered the #HMBALMANATION.
