The Pirates Of The Caribbean star Keira Knightley has posed topless for the cover of an upcoming U.S. magazine. The British beauty was shot for the cover of December/January issue of Interview magazine by Sam Taylor-Wood. The 22-year-old actress is covering her nipples with braces and a gloved hand for the raunchy cover-shot. Keira, when asked upon the subject, joked it off. "We ended by taking my clothes off. Why does that always happen? Because I say yes, I suppose!" she said.
