Cara Delevingne has always idolised Kate Moss.

The 21-year-old star looked up to the British supermodel as a young girl and reveals she used to dream of being as cool as Kate in the latest trailer for the iconic star's new Topshop collection.

Cara says in the video: ''I just knew exactly who she was of course, she was the face, she was the icon. Everyone just wanted to dress like Kate, and she kind of brought that to the [Topshop] collection, made everyone be able to have that style that she has, which is just incredible.''

The short film sees Cara muck around with a tennis ball, lounge around in bed and perform a somersault as she discusses her fashion icon.

The bushy-browed beauty has constantly been compared to Kate since her meteoric rise to fame, and is now one of the world's most in-demand models, walking the runway for the likes of Chanel and Dior, and featuring in campaigns for Mulberry and Burberry.

Kate and Cara have also joined forces for the first time ever in an upcoming fragrance ad for British brand Burberry.

This is just the latest in a series of eight short films with Nowness, which see famous faces like Dame Vivienne Westwood and Net-a-Porter founder Natalie Massenet discuss Moss's influence on the fashion industry.

Kate's 2014 Topshop spring collection hits stores on April 30 and will be available online from the Topshop, Net-a-porter and Nordstrom websites.
