Gigi Hadid's Sexy Lip Sync Battle Outfits Will Have You Saying "Backstreet Boys Who?"

As proud children of the '90s, we typically freak out whenever any of the Backstreet Boys appear reunited on stage. But when two of them — Nick and A.J. — sang alongside Gigi Hadid during Spike's Lip Sync Battle, we almost uttered the words "Backstreet Boys who?"

It was an easy crime for any BSB fan to commit: just take a look at what Gigi wore! Her shiny black bodysuit hugged every curve and was perfect for her performance where she sexily swayed on a motorcycle. But it wasn't just that one-piece that caught our eye. Gigi also appeared on stage in distressed boyfriend jeans, strappy heels, and a suede fringe top for the Ting Tings' "That's Not My Name" — a look that moved along with her as she danced. We're not saying it was the outfits that helped her claim victory at the end of the night, but they definitely helped.

Read on to get a good look at Gigi's style from the show. Then, head over to see how the model has been slaying Fashion Month, one catwalk at a time.
