Angelina Jolie's brother, James Haven,is insisting his sister has found the perfect partner in Brad Pitt, and he expects them to stay "together for life." The Hollywood star began dating sexy Pitt in 2006, shortly after he divorced 'The Bitch' Jennifer Aniston. The happy couple now has six children with each other. And Haven is convinced the pair will never split up, because Pitt has had such a positive influence on Jolie's life. He says, "Brad has changed my sister a lot. They have an extraordinary bond. I've never seen any sign of tension between them and if it keeps going the way it's going, they'll be together for life."
