Jude Law and Sienna MillerSadie Frost is apparently livid that ex-husband Jude Law has hooked up with Sienna Miller again because she doesn’t think the couple have a future together.

A close source told Grazia magazine that Sadie emailed Jude, telling him Sienna will never be able to make him happy: “Sadie said he was mad to go back to Sienna. She said he really changes when he is with her, he becomes stressed and emotionally all over the place.”

Jude then apparently showed Sienna the message and Sienna replied, accusing Sadie of being jealous and ordered her to “get over it”.

That was too much for Sadie so she picked up the phone: “Sadie called Jude and screamed ‘I’m not going to be there to nurse your wounds when she drives you mad - and it will happen’.”
