Unless you happened to pick up a copy of Interview back in September, you might have missed Keira Knightley's gorgeous photo spread in which she appeared wearing a pair of slim-cut black pants -- and nothing else. And now, she's opened up about her choice to bare her breasts in the magazine, for basically the best reason ever: that it was a way for her to fight back against having her assets digitally enhanced.

In an interview with The Times of London (reported via Hollywood Life), Keira said of the pic, "That was one of the ones where I said, 'OK, I’m fine doing the topless shot so long as you don’t make them any bigger or retouch.' Because it does feel important to say it really doesn’t matter what shape you are."

That sound you hear is every A-cup lady on earth, applauding with wild approval.

Meanwhile, Keira had still more insightful things to say about her decision to take it off, and her frustration with having her body manipulated digitally to be something it's not:

"I think women’s bodies are a battleground and photography is partly to blame," she explained. "Our society is so photographic now, it becomes more difficult to see all of those different varieties of shape."

All the kudos go to Keira for unveiling her variety of shape, without Photoshop and without apology. Without saying a word, her photo says everything you need to know about the beauty of bodies of all types and sizes. If you want to see the sultry shoot for yourself, the pics are live now on the Interview website.
