There were rumors the gruesome twosome would be moving in together back in December, but now it's official!
"Sienna has already moved most of her stuff into Jude’s place which is very close by," said a friend of Sienna's.
"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."
Those are some serious steps for a homewrecker and a cheater to take!
