Jude Law, Sienna Miller Call It Quits (Again)

A rep confirms that the on-again, off-again couple are now off.

The second time apparently wasn't the charm for Jude Law and Sienna Miller, as the British actors have officially split up again.

"I can confirm that Jude Law and Sienna Miller are no longer in a relationship," Law's rep tells People.com. Meanwhile, a source close to the two stars gives a little more insight into the latest drama they are facing.

"It is mutual and amicable and they are still friends," the source said. "It was entirely an end-of-the-relationship decision. It had run its course."

Law and Miller initially began dating in 2004 after meeting on the set of "Alfie." That same year, they got engaged over the Christmas holidays. However, two years later the pair faced some scandal when Law confessed to cheating on the British starlet with his kids' nanny.

"It's dangerous to bring this up. I talked about him in an interview not long ago, saying that I still love him, and he was like, 'Please stop talking about it.' ... That was a very pivotal time in my life, and I'm happy saying that. It's a private moment when you get your heart broken for the first time, and that was the absolute antithesis of private,"

In the same interview, Miller confessed to being a hopeless romantic, regardless of how she may come across in the media. "I've actually never been taken on a date in my whole life. I have never had a one-night stand. I'm a real relationship person — contrary to public perception," she explained. "I'm either in one or I'm not. I get kind of emotionally involved very quickly, and I'm not going to spend time with someone unless I love them. But it's not hard for me to fall in love."

Later in 2009, Law and Miller reconciled when both were starring in Broadway shows in New York City. No reason was given for their latest split.
