Knightley tops perfect pout poll

"Pirates of the Caribbean" actress Keira Knightley is voted the most perfect pout and Leslie Ash the worst in a recent poll.

According to thesun.co.uk, Knightley beat the likes of Angelina Jolie and Kylie Minogue in a poll of 3,000 women.

Keira had famously said: "I don't pout to be sexy. I do it when I'm concentrating. I think it makes me look constipated."

Leslie Ash had got a 'trout pout' after an allergic reaction to collagen injections. She was followed by troubled British singer Amy Winehouse.
