Keira Knightley had a "great" time shooting the latest perfume advert for Chanel.

The British actress - who is the face of the French fashion house's Coco Mademoiselle fragrance - was initially very nervous about working with the brand, but has now relaxed after the first advert was well received.

She told Stylist magazine: "It was great. We've just done another one and it's brilliant. With the first one I think we were all a bit worried because we didn't know if it was going to sell well and it was taking over this enormous thing.

"It was quite frightening. But the latest one, because we went with the same team we had a really lovely time."

The 25-year-old beauty - who is well known for her glamorous red carpet looks - admits she only really enjoys promoting a project if she has to do it rarely, as she has a "scruffy style".

She said: "It's always nice to have an occasion to wear a silly frock and get dolled up but I'm not really that sort of person. Style? I don't have any. Well, I'm scruffy."
