What Do Brad’s Parents Think of Angelina?

When Brad Pitt's parents attended the premiere of In the Land of Blood and Honey, People asked them what they really thought of Angelina Jolie. Despite all the rumors of tension between them, Bill and Jane Pitt responded by saying how proud they are of her, according to monsstersandcritics.com. They went on to say that she's a 'really good mum'.

I would imagine that even if they had something negative to say, they probably wouldn't, and they certainly wouldn't at the premiere of her directorial debut. It does seem that they get along when they're in public. Do you think they get along when the cameras are off?
