Sienna Miller is the first to admit she's made some questionable decisions in the past. Reflecting on her life in the March issue of Esquire U.K. -- out amid new revelations about her alleged 2005 affair with James Bond actor Daniel Craig -- the British beauty says she nearly ruined her professional life by not "behaving the way you should" in her personal life.
"I sabotaged things. I burnt a lot of bridges," the Alfie star tells the magazine of letting her rocky relationships in the early 2000s overshadow her acting resume. (Her first high-profile romance was with Jude Law, from whom she split after he was revealed to be cheating on her; she later dated Rhys Ifans and had an affair with Balthazar Getty, who was married at the time and has four kids.)
"On set, I was first to arrive, last to leave, best friends with the crew, totally professional, no dicking around. But when I wasn't at work, I wasn't behaving the way you should," she confesses. "I'm very lucky to have a second chance in that town...It was really bad. What was going on in my private life was not an easy thing to read about. People don't want to see films with people they don't approve of in them."
"But it's not like you've actually done anything immoral, have you?" the interviewer asks. To which she replies, "No, no, no, I have."
After a rough few years in the spotlight, she says, she was sick of herself. So she took a break from film and signed on to star in the play After Miss Julie, which was playing in New York at the same time that her ex-fiance, Law, was acting on Broadway in Hamlet. They ended up getting back together for several months, despite having parted on bad terms three years earlier.
"When something ends in a way like that, it's important if you can, in a way, go back and revisit it and either shut that door or create a new room. So it was a very healthy, cathartic experience," she says of their reconciliation. "And I think it paved the way for both of us to have great futures with no animosity or drama. Such a huge relief, to heal that. And I'm great friends with him and with his children. I love them, madly. Just huge love and respect for all of them." (The Dom Hemingway actor has three kids from his marriage to Sadie Frost, and a daughter from a relationship with model Samantha Burke.)
These days, the 32-year-old actress is happily engaged to actor Tom Sturridge, with whom she has a daughter, Marlowe, 18 months. "I feel really settled. I have a wonderful life. I'm up every morning with a little baby," she tells Esquire. "That gives you incredible perspective. It's such a gift. And it's grounding in a way you can't describe."
Of her fiance, she says, "He's the antithesis of me, really. And that's a first for me, to be in a relationship with someone who's in a lot of respects very different. He's the perfect balance to my lunacy, which makes him sound really boring, but he's not, at all. It's good, it works. It's not easy, of course, but we're a family and I love that. I wake up and I'm like, 'I'm a family, I'm a grown up!' I still can't believe it."
