Jolie, 31, says that she and Pitt, 43, have different parenting styles when it comes to Maddox, 5; Zahara, who turns 2 on Jan. 8; and Shiloh, 7 months: "I am the disciplinarian," she says. "Brad can be, but if Z doesn't get the bottle from me, she'll very quickly run to Daddy."
Asked which of the three kids rules the Jolie-Pitt roost, she says, "I bet if you asked Brad, he'd say Zahara. Mad is very smart, but he's got a certain sense of calm. Zahara is possibly the funniest person I've ever met in my life. So dramatic and creative and loud and charming. She's definitely the biggest personality in the house."
More on Angelina & Brad
Jolie admits that their humanitarian and film work creates a somewhat nomadic existence for their family. "It's hard, and maybe one day we'll have to stay in one place," she says. "I'm sure (the kids are) going to be 18 and say, 'God, I just want to stay in one place.' They'll never want to leave home!"
But for now, they're not slowing down. On Wednesday, after the prosecutor of the International Criminal Court announced plans to indict suspects for atrocities in Darfur, Jolie released a statement urging Americans to support the effort: "The Prosecutor is offering justice."
On a recent visit to Cambodia, where the couple are sponsoring a relief project in Maddox's name, "He recognized himself in the people," Jolie says of her son. "Which is a wonderful thing."
