Sienna Miller has said she wants to be seen as a woman when she turns 30 this year, but accepts it is up to her to make it her more serious decade.
The actress and designer - who caused controversy when she remarked that people take drugs because they're "loads of fun" and has confessed to spraying the paparazzi with a water pistol filled with urine - told Australia's Herald Sun newspaper she is ready to grow up.
Sienna said: "I can't wait to be seen as a woman. But I know I probably have to contribute to that with behaviour."
She added: "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.
"Now, I'm much more calm. It feels like a new, more serious decade."
And the actress, who starred opposite her then boyfriend Jude Law in a remake of Alfie, hopes her acting career is something she can also build on as she matures.
She said: "I've definitely had some turkeys. I'd be lying if I said that wasn't disappointing. But I've also made films I'm really proud of."
Sienna and Jude dated after meeting in Alfie in 2004 but split shortly after he was revealed to have had an affair with his children's nanny in 2005. They rekindled their romance in 2009 but split again earlier this year.
She said: "I think that happens in everyone's lives. You get back together, you try to make it work, and it doesn't. It's run its course."
