Keira Knightley's American dream continues with her latest photoshoot for W magazine.

The 22-year-old actress, who is known for her love of posing naked, once again appears provocative, with one cover revealing her well-toned navel while wearing a denim bondage suit.

In 2006, Keira stripped completely for a Vanity Fair cover alongside actress Scarlett Johansson, and has since done racy shoots for Coco Chanel and Interview magazine.

In another W cover photo, she poses with Atonement co-star James McAvoy.

Their film leads the list of BAFTA nominations this year, with Keira battling Cate Blanchett among others for Leading Actress.
