Washington, Feb 23 : Actress Sienna Miller has vowed never to go under the knife to enhance her looks.

The Factory Girl slammed the beauty-obsessed culture in Los Angeles, and expressed her shock at the lengths some women go to just to stay looking young.

The 27-year-old star said that she was determined to grow old gracefully.

"I found myself thinking, ''I''m getting wrinkles and things are wobbling - I should go to the gym'. Then I was like, ''No way.'' It''s not where the focus should be right now," Contactmusic quoted her as saying.

"Girls in L. A. are having pre-emptive Botox. Let people be young and then old. I can''t wait to be seen as a woman," she added. (ANI)
