Keira Knightley not against plastic surgery

London: Actress Keira Knightley says she doesn't intend to go for plastic surgery but she won't condemn those who go under the knife to look better.

The 29-year-old admits that surgery can restrict facial movements. But if it makes people happy, they are free to try it, reports femalefirst.co.uk.

"It is a drawback, not being able to move your face. But I don't think I would ever condemn any woman for doing something that made her feel better about herself," she said.

"If she's suddenly feeling like she's the most disgusting thing in the world, and that's what she wants to do and that makes her happier, then I think she should be free to do what makes her feel better in her own body, her own skin and own mind."

Asked if she would ever consider going under the knife, she said: "Surgery for myself? I hope I don't. I don't plan to. But who knows?"
