Keira Knightley has topped a poll of perfect pouts.

'The Duchess' star beat 'Wanted' actress Angelina Jolie to the number one spot in a public survey by lip care company Blistex.

Knightley (23) has previously said she doesn’t think her pursed lips are attractive, claiming it makes her look like she is having trouble with her bowel movements.

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

Pop princess Kylie Minogue took third place in the poll of 3000 women.

The worst pout slot went to British actress Leslie Ash, who suffered an allergic reaction to collagen injection. She was closely followed by troubled singer Amy Winehouse and British glamour model Jodie Marsh.
