We've seen a few shots of Keira Knightly shooting the latest Chanel Coco Mademoiselle ad campaign in the streets of Paris, and yesterday we gave you a glimpse of her talking about the fragrance. We can't wait to see the full commercial - directed by Joe Wright - and to tide you over until the release of the full-length video, we have a sneak peek preview! Keira says nobody knew what it was going to be like - "It was completely unexpected, it's a Chanel superwoman." Check out the preview and stay tuned for the finished product, coming soon . . .
