With her toned torso on show for all to see, the blonde beauty also sported a printed monochrome pencil skirt.
Finishing just below the knees, the number clung to all the right places on her petite frame.
A pair of black strappy heels accentuated her model height, while she kept the rest of her accessories to a bare minimum.
Jennifer wore her luscious long locks out styled in loose waves with a side part.
A slick of light pink lipstick and lashings of bold black mascara completed her picture perfect look.
Meanwhile, Gaultier was also dressed to impress in a sleek black leather jacket teamed with a charcoal shirt.
Proving colour coordination is the way to go, he also sported a pair of black trousers and matching shoes as he stood against the media wall.
As the host of Australia’s Next Top Model, Jennifer was quite the hospitable host as she welcomed Gaultier at the event.
Putting their arms around each other, the pair chatted and giggled as the cameras snapped away.
Also at the event was the reality show’s judge Alex Perry, who also decided to inject some colour into his look.
The local designer sported a black T-shirt with a bold monochrome print along the neckline and three bright yellow stars imprinted over the top.
He also opted for sleek black trousers and shoes, and of course his signature accessory of dark sunglasses worn on his head.
Gaultier is one of many big name stars who will feature in the new season of Australia’s Next Top Model.
