Sienna Miller just too wild for Jude Law

On Sunday, Jude Law and Sienna Miller split for good, a source close to the pair spilled to PEOPLE.

"It's a mutual decision," a pal of the actor says. "They have definitely come to the end of the road. They tried to make it work but it failed."

PageSix meanwhile reports it was Jude Law who called off his rocky relationship with Sienna Miller.

"She was just too wild for him," said an insider. "She partied too much. He is a devoted father of four children and she always wanted to go out constantly. He was just done with her."

Miller, 24, dumped Law, 33, the first time around, breaking off their engagement in the summer of 2005 when he confessed to having an affair with his children’s nanny, Daisy Wright.

The on-off couple reunited again last May.
