Watch New 'Mademoiselle Privé' Chanel Video

French fashion house Chanel has released a new video featuring famous ambassadors of the brand wearing a special collection of jewellery, ahead of the opening of a new exhibition next month that celebrates the fashion label and its creative director, Karl Lagerfeld.

The video, released earlier this week, captures behind-the-scenes footage during a photoshoot with Lagerfeld, as well as interviews with the ambassadors who talk about their experience of working with the man himself.

The Chanel stars, including actress Kristen Stewart and model Lily-Rose Depp, are all filmed wearing reissued "Bijoux de Diamants" jewellery collection—the first and only fine jewellery collection designed by the brand's founder Gabrielle Coco Chanel in 1932.

The re-editions of the jewellery will go on display at the Saatchi Gallery in October as part of the "Mademoiselle Privé" exhibition. The show will be displayed over three floors of the gallery located in west London, and will highlight the brand's history including its famous Haute Couture and its Chanel No.5 perfume.

Speaking about the shoot with Lagerfeld, Kristen Stewart said, "Once [Lagerfeld] sees something, you could be done in five minutes and you don't even realise you've finished the entire thing because he just knows exactly what he wants."

Lily-Rose Depp added, "What's so incredible about shooting with Karl is that he really knows how to bring out the best in someone, which then brings out the best in the clothes."

The shoot also stars Keira Knightley, Vanessa Paradis, Lily Collins, Julianne Moore and Alice Dellal, among others.

Mademoiselle Privé will open at the Saatchi Gallery in London on October 13 and run until November 1.
