Miller: I've been immoral

London - As former boyfriend Jude Law testifies about her cheating scandal with James Bond actor Daniel Craig, British actress Sienna Miller admits she has derailed her Hollywood career by not "behaving the way you should" in her personal life.

Miller and Law called off their engagement in 2005 after the actor cheated on her with nanny Daisy Wright and rumours spread about the actress' affair with Craig. The affair is back in the media spotlight after Law, 41, was told at Britain's phone-hacking trial on Monday that his close relative had sold stories about Miller, 32, and Craig, 45, to News Of The World tabloid.

In an interview with the March issue of Esquire magazine, for which she posed topless, Miller said: "I sabotaged things. I burnt a lot of bridges."

She was quoted as saying she was "very lucky to have a second chance" in Hollywood, after achieving tabloid notoriety. After Law, she dated actors Rhys Ifans and Balthazar Getty, who was married with four children then.

She said: "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."

When told she had not done anything immoral, she said: "No, no, no, I have."

After acting in films such as Casanova (2005) and G.I. Joe: The Rise Of Cobra (2009), she starred in a play in New York in 2009 and reunited with Law, who was also acting on Broadway then. She said their one-year reconciliation was "cathartic" and helped them heal, after the "awful" way their engagement ended.

Miller, who stars in upcoming films Foxcatcher (with Channing Tatum) and Business Trip (with Dave Franco), is now engaged to actor Tom Sturridge, 28. The couple have an 18-month-old daughter. She said her fiancee "is the antithesis of me, really".

"And that's a first for me," she added, "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."
