Now, a friend of the actress says: "Sienna has instructed estate agents Foxtons to put her London house on the market and has decided to move in with Jude. She had it up for sale last year but it didn’t sell."

Sienna has barely stepped through the door of the two-bed ‘bachelorette pad’ in Maida Vale, West London, since she and Jude re-united in New York - where they had been working on Broadway.

"Sienna has already moved most of her stuff into Jude’s place which is very close by," the friend says. "She spends every waking moment with him and that’s the real reason why she wants to get rid of the Maida Vale place. They are back on track and living together is the next step. They had an amazing holiday at Christmas and made a decision to commit to one another. Jude has vowed that his cheating days are behind him and Sienna has begged her family to give him the benefit of the doubt, even though he let her down last time."
