London, May 17 : Actress Sienna Miller has revealed she can't wait to put her 20's behind her and embrace her 30s, even though she is worried about ageing.

The 29-year-old will reach the milestone age in December and after a series of unsuccessful love affairs, including relationships with Jude Law and the married Balthazar Getty, she is looking forward to have a serious career, reports femalefirst. co. uk.

"I think, if you put a camera in anyone's life and document it daily from the age of 21 to 27, there are going to be things that aren't always pretty. I feel as though I experienced my 20s in all their glory and all their disastrousness. Now, I'm much more calm. It feels like a new, more serious decade," she said.

"Things just come out. I'll say the most inappropriate things at the most inappropriate time to the most inappropriate person. Always. I can't wait to be seen as a woman. But I know I probably have to contribute to that with behaviour," she added.(IANS)
