I recently heard that she's been trying to get far away from her ex because she's terrified of him. Don't know how true that is as I've never followed her story and don't know anything about her private life, but that's what the tour guide guy said to those of us who were on a Hollywood guided tour bus a few days ago, when we went by her house. If it's true then I don't blame her wanting to get well away from him if he's violent and threatening!! But who knows.
If he had been violent, then I'm sure that would have been brought up and used against him before. If she's been spreading false rumours to win sympathy, then she's totally unhinged.
