The 22-year-old model is reportedly set to star in the upcoming comedy sequel with Ben Stiller and Owen Wilson, reports E! Online.

The duo announced they were filming 'Zoolander 2 ' when they took to the runway in character as Derek Zoolander and Hansel McDonald for Valentino at Paris Fashion Week on Tuesday (10.03.15), although they are yet to confirm whether the blonde beauty will star alongside them in the movie which is due to hit cinemas in Febraury 2016.

It is thought the role was offered to fellow model Gigi Hadid before being accepted by the former Victoria's Secret Angel.

Bosses are also said to have been in talks with Naomi Campbell, Cara Delevingne, Jourdan Dunn and Alessandra Ambrosio to appear in the picture.

The movie - which will come 15 years after its predecessor - is being directed by Stiller and has been written by Jennifer Aniston's fiancé Justin Theroux.

Meanwhile, Ben, 49, and Owen, 46, delighted their unsuspecting audience as they strutted down the catwalk as their alter egos for the luxury label's A/W 2015 show.

A source said: "It was hilarious. People freaked out...

According to the onlooker, the music at the show suddenly switched to 'Don't You Want Me' by the Human League and the two actors stepped out and walked the entire runway, before receiving a standing ovation as the other models stepped out for the finale.

One stylist was overheard saying: "It's about time there is some humour in this industry."

Ben, as Derek, wore a custom Night Butterflies brocade suit with hand-embroidered overcoat and black Creeper shoes, while his co-star, as Hansel, donned a Silk Continent print pyjama suit with Double Cashmere overcoat and Open sneakers.
