So let us recount that time the Backstreet Boys surprised the world by popping up at the Balmain x H&M fashion show in NYC. Sure, the runway was populated with supermodels like Real Housewives of Beverly Hills daughters Gigi and Bella Hadid, Kendall Jenner, Jourdan Dunn, Joan Smalls, and Karlie Kloss rocking hot, we've-got-to-have-them fashions, but the real highlight for those who attended the Tuesday show (October 19) to be when BSB hit the catwalk to perform. They treated everyone to "I Want It That Way" and “Everybody (Backstreet’s Back).” Footage posted online shows the fivesome wowing the very lucky crowd with their performance — which, BTW, left BFFs Gigi and Kendall swooning, as evidenced in the video below.
Of course Gigi had a blast.
