There’s one problem: For years now, Angelina, 50, has had her heart set on moving to London.

“She was just waiting for the divorce and custody issues to be resolved and for Knox and Vivienne to turn 18,” a source says of the former couple’s twins, who will turn 18 next July. “Now Brad and Angie are on this collision course.”

That is, unless Angelina rethinks her plans.

“She just might,” says the source, “because the last thing she probably wants is to run into Brad. There’s still a lot of pain there — she can’t seem to forget what he did or forgive him.

“Angie scouted out many other places in Europe when she was plotting the move, so she could end up anywhere.”
