I'm the first Backstreet Girl!' Gigi Hadid wins Lip Sync Battle after performing Larger Than Life in black catsuit with Nick Carter and A.J. McLean

performed in a skin-tight black catsuit on Thursday as she easily beat Tyler Posey in the latest episode of Lip Sync Battle.

The 20-year-old pulled out all the stops as she performed the Backstreet Boys hit Larger Than Life along with group members Nick Carter and A.J. McLean.

Gigi showed off plenty of cleavage in the sexy and figure hugging outfit as she took on the boyband's 1999 hit.

My life is complete first of all. Second of all I am officially the first Backstreet Girl,’ Gigi laughed after her performance.

'Honestly this was one of the best nights of my entire life,' she said as she strapped the title belt around her waist.

Tyler earlier in shorts, a flannel shirt and backwards cap kicked off the show with Harvey Danger’s 1997 alternative hit Flagpole Sitta.

Gigi cheered on her opponent as she danced behind him on stage with host LL Cool J.

'I'm gonna go and throw up,’ Tyler said after his energetic performance.

'You killed it that was amazing,’ show commentator Chrissy Teigen told him as he caught his breath.

Asked if she was scared of wolves, Gigi laughed and told LL Cool J that Tyler was 'not that hard to look at, so its fine.'

Gigi then took on That's Not My Name as she strutted her model moves across the studio.

'Too many talents, you can do so many things, you are so talented,' Chrissy told her.

'Damn, it was pretty fantastic,’ Tyler said about Gigi dancing up on him and pretending to slap his face during her performance.

Tyler backstage said when he was 17 he was in a TV show where he had to dance and was 'awful' at it.

'I am happy to redeem myself. I just want to do this, this is just so much fun,’ he told the cameras.

Tyler then grabbed a black leather jacket to perform the 1984 A-ha classic Take On Me as Gigi sang along with the words from the VIP seats.

'Literally never change, this should always be your style,' Chrissy told him as she chased him around the stage in a cleavage-baring dress.

Gigi was confident that she could do better though.

'What I am bringing is like, that was good, but like…' she said smiling.

In backstage footage Gigi told the cameras she was 'kinda scared and trying not to forget the words.'

She went through her dance steps in a barely there sports bra before meeting up with her stepfather, David Foster, who was watching on.

Gigi last month posted an Instagram video of herself with her young niece and sister Bella all singing along to I Want It That Way by the Backstreet Boys.
