Last week we revealed a few images from Keira Knightley's new Chanel Coco Mademoiselle fragrance campaign. Now here is a little something more to spark your interest - a teaser video from the commercial. In this clip, the actress talks about her expectations of the campaign. "Nobody said exactly what it was going to be like," she says. "I knew that it was something about a motorbike, and I knew it was going to be beige, and they said: 'sort of catsuit'".

This is just a hint of the three-minute commercial which was directed by Joe Wright (Pride and Prejudice, Atonement) and is set for release on March 21. Together with Blake Lively's Chanel campaign and the Chanel show, it's been a big week for the French fashion house.
