During the Balmain x H&M fashion show in NYC tonight, guests were taken back in time with a surprise performance by the Backstreet Boys.

The group, decked out in pieces from the upcoming collaboration, performed hit singles like “I Want It That Way” and “Everybody (Backstreet’s Back).”

Check out some of the videos and images from the performance below. And keep it locked to Complex to find out what else went down during the event.
