Knightley blames pout on nerves

London, May 7 (IANS) Actress Keira Knightley, who has appeared in hits like "Bend It Like Beckham" and "Pirates of the Caribbean", blames her seductive pout on nerves and feeling tense.

Knightley is famous for her moody looks and bee-stung lips, but she hates that look and clarified that she does not do it on purpose, thesun.co.uk reports.

She said: "I think I was pouty when I was 16 or 17, when my first films came out and it's sort of stuck. I don't know, maybe I still do it. It's when I'm nervous and my neck gets really really tense and then that pressure sort of squeezes up to my lips and they push out and well, there you go, that's the pout."
