According to The Sun, the gruesome twosome have been meeting in secret at the Algonquin Hotel in NYC during rehearsal breaks from their plays on Broadway.

A source said:

"Last week they put the wheels in motion to live together again.

 

"They have told staff that they are in love and will be moving back to London in the spring and they will be living together as a couple once again."

Lucky staff. We can't imagine that they'd give a fuck, though...

The source added:

"Jude was reluctant at first for anything to happen. But Sienna convinced him that she was still in love with him."

Well, we all remember what happened last time (Jude slept with the nanny, Sienna reportedly got her own back by bumping uglies with Daniel Craig).

We give it until their time on Broadway is up...
