Settle Down Sienna

This time around, it was Jude Law who called off his rocky relationship with Sienna Miller claims Page Six. "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. After the publication of Wright’s diaries, which detailed her three-month fling with the actor, the two parted ways and Miller took up briefly with her Camille costar James Franco.

The on-off couple reunited again last May, but are now over for good, according to friends of the duo. Reps for Miller and Law declined to comment on the couple's latest split.
