Hollywood actress Keira Knightley holds her nervous temperament responsible for her famous pout.
However, the 23-year-old actress insists that she hates her pouty looks and doesn't do it deliberately.
"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," Contactmusic quoted Knightley, as saying.
"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," she added.
Meanwhile, the actress revealed that she was ashamed of the 'Pirates of the Caribbean' franchise when she first signed the films - because they were based on a theme park ride.
Pierce Brosnan is 'outrageously' kissable! Legendry actor Pierce Brosnan may not be attached to the 'James Bond' film series anymore, but he is still considered to be one of the most kissable men in Hollywood.
