Still, there is a downside to all this globetrotting.
"After the flight from Europe," Jolie told the German edition of Vanity Fair, "we were all suffering a bit from jetlag. Although we went to bed early, [the kids] were up at 4:30 a.m. goofing around."
After moving their brood from a chateau in the south of France to a palace in a park in Berlin, the family landed in New York last week for the premiere of her movie Changeling – then jetted back to France Wednesday.
Jolie, 33, admits to having an expert travel arranger: "Brad took care of things. He just said, 'Go back to sleep, you have to work tomorrow,' and then went to the living room with the kids. He's an amazing father: totally devoted."
The Challenge of TwinsJolie calls caring for twins a challenge. "We're exhausted a lot, because it's twice as hard with two babies than with one," she says. "But it's twice as much fun, too."
That means watching them interact. "When you look at them, it's like they were made for each other," she explains. "They smile at each other, sniff each other, touch each other. It's just beautiful."
Even at their tender ages, they are each displaying distinct temperaments. "They're totally sweet. They already have completely different personalities. Knox is more the quiet one, very relaxed, while Viv is a little more aggressive and loud," she says.
And as for the inevitable question, "It's funny," Jolie admits, "Knox looks more like Brad and Viv more like me."
