A few days ago, Spike TV teased that Backstreet Boys members Nick Carter and AJ Mclean would make a guest appearance on Lip Sync Battle alongside Gigi Hadid. If you were itching for more of the '90s pop-referencing performance, the full video is now here!

On last night's episode of Lip Sync Battle, the supermodel/pop star girlfriend/Swift squad member went head-to-head with actor Tyler Posey. 

Gigi pulled out the big guns by donning an intense black latex catsuit and enlisting the real deak BSB members for her "Larger Than Life" performance. As for Tyler? The leather jacket-rocking Teen Wolf star opted to go the '80s route, as he joyously shimmied his way through A-ha's classic hit/karaoke staple, "Take On Me."
