Keira Knightley bares all for Chanel

As she would be the first to admit, Keira Knightley is not exactly famous for her hour-glass figure.

But her latest role - which sees her posing virtually naked to advertise a perfume - makes her look subtly different.

Despite the presence of a carefully-placed bowler hat, the 22-year-old actress appears to be just that tiny bit curvier.

It's certainly a different image from that presented in such hit films as Pride And Prejudice and the Pirates Of The Caribbean series.

Ever since she appeared in a sports bra as a 17-year-old in Bend It Like Beckham, the waiflike actress has done nothing to disguise her lack of cleavage.

She once spoke her dislike of her chest, saying: "I don't have any t***, so I can't show cleavage."
That's not always something the Hollywood publicity machine has been happy about.

While the British posters for her 2004 film King Arthur displayed her natural boyish look, the American ones were a different story.
