Law and Miller Split

Jude Law and Sienna Miller have reportedly split for good, blaming "fundamental differences" for the end of their three-year relationship.

The actress broke off her engagement to Law in 2005 after private diaries of the couple's nanny, Daisy Wright, were made public in the New York Post.

Wright's extremely detailed account of her three-month affair with Law left his relationship with Miller rocky, though the twosome eventually reunited.

According to friends, the pair decided to end the relationship after a crisis meeting last week.

"She was just too wild for him," dished one insider. "She partied too much."

A source close to the couple tells British newspaper The Daily Mirror, "Jude and Sienna decided it was over last week.

"Basically they had fundamental differences in their approaches to life.

"It was a mutual agreement because they both thought the relationship had run its course. It's very sad for both of them.

"They both tried and tried to make it work but they couldn't see a future together and decided to separate."

He is a devoted father of four children and she always wanted to go out constantly.  Miller, who was recently spotted lunching with Dustin Hoffman and Sean Penn, was previously the one doing the dumping.
