Sienna Miller only agreed to holiday with Jude Law and his children if he left their nanny at home. Sienna Miller joined Jude Law - whom she broke off her engagement to in 2005, after she found he had cheated on her with his children's carer Daisy Wright - in the Caribbean, but only after he agreed to her ultimatum.

A source of Daily Mirror newspaper revealed: "Haunted by what happened the last time they were together, Sienna is leaving nothing to chance second time around." The source also added that Sienna Miller wants her and Jude to work on their 'friendship' first, before she and Jude jump to love boat again.

The source adds: "Sienna (Miller) wants it to be just her and the family, and for them to have a quiet, low-key celebration together." Photo: Sienna Miller was spotted by photographers in New York City on December 17, 2009. Photo: Fame Pictures
