Angelina says she never wanted biological children -- until she fell for Brad. The "Changeling" star was satisfied with her adopted brood until, "I just looked at him and loved him and just felt open to (getting pregnant)," she tells W magazine. "I suddenly wanted to. It's one of those things you can't explain."
Jolie, 33, explained that when cutie kids Maddox and Zahara bonded with dad Brad, "I knew that he would never see them as different, and that gave me a certain peace."
Add toddler Shiloh and 3-month-old twins Knox and Viv, and there isn't much peace in the house, but it's exactly what Angie wanted. "I wouldn't trade that experience for the world," she gushed.
