Gigi Hadid brought out all the stops in her Lip Sync Battle with Teen Wolf star Tyler Posey!
The 20-year-old supermodel was joined onstage by Backstreet Boys' Nick Carter and A.J. McLean for her performance of "Larger Than Life," but it’s her super sexy outfit that ensured all eyes were still on her. Gigi sported a jaw-dropping leather catsuit for the episode airing this Thursday at 10 p.m. on Spike, flaunting her incredible physique.

And judging by Tyler's enthusiastic fist-pumping, even her competitor was wowed by Gigi's performance.
ET chatted with A.J. in January at the premiere of The Finest Hours in Hollywood, California, where he revealed how his surprise appearance on Lip Sync Battle came about.
"We met Gigi for the very first time at the Balmain event up in New York, and she asked us to do it and I'm like, 'Of course!'" A.J. explained. "So, I said, 'The next time the Backstreet Boys have any kind of video, you gotta return the favor and be the main girl in one of our videos,' and she said, 'Absolutely, for sure.'"
Of course, Gigi's already been the main video girl for her boyfriend, former One Direction member Zayn Malik. Watch the video below to see the couple show some serious PDA in Zayn's super sexy video for his hit, "Pillowtalk."
