Keira Knightley has confessed that a photo of her in a new advert has been altered to increase the size of her chest.

The advert for Chanel`s Coco Mademoiselle features the star kneeling down with just a bowler hat covering her front.

However, the Bend It Like Beckham actress has admitted that she allowed the advertising team to fix the pictures to make her bosom look more ample.

She commented: "Those things certainly weren`t mine. We had an interesting discussion when they said, `We want to make them slightly larger and you`ll get approval` and I was like, `OK, fine. I honestly don`t give a s**t."

The actress added: "I don`t have any t**ts, so I can`t show cleavage."
