Only four months old, Angelina Jolie and Brad Pitt's twins, Knox and Vivienne, are already starting to show off their personalities, the actress said in a recent interview.

"They’re great. They’re still so little, but they do [have their own personalities].  They’re at that [stage] where their personality really starts to shine," the world-famous mom said Sunday at the "Kung Fu Panda" DVD release party in Los Angeles. "So it is very fun."
Sporting a black mini dress, the mother-of-six looked radiant at the event, and revealed her secret to looking good while chasing her brood! "A lot of good under-eye concealer," Jolie laughed.

Speaking about life with so many children around, the actress said they like to do "lots of things" together as a normal family, including staying at home and playing. The children, Maddox, 7, Pax Thien, turning 5 this month, Zahara, 3 and Shiloh, 2, also enjoy watching movies, especially "Kung Fu Panda," which they loved even more because their mother voiced the character Tigress.

"My kids do love it," Jolie told Usmagazine.com, "They are very, very proud. They have mom dolls everywhere. They have the Tigress. They love Tigress. They have a big Tigress doll that they keep putting diapers on! They love Tigress!"

The "Changeling" star also talked about having more children, "Anything could happen," she told Access Hollywood. "We’re open to anything, we love kids and we’re having a great time… It’s chaos in our house, but it’s so much fun. We’ll definitely have more."

Speaking of her partner, Jolie praised Brad Pitt's fathering skills, "He's the best daddy and we have fun, so whenever it gets hard we can just look at each other and find a way to laugh and just appreciate that they're only little once, and we should enjoy every minute."

Asked if she plans on adopting again, Angelina admitted it will be a "giant" surprise for all of us. "I'm one of the most fortunate people in the world. My children are healthy. I have love in my life. I have no reason to be anything but very grateful and happy so I'm a lucky woman."

The same event, held at Grauman’s Chinese Theatre, reunited Jack Black, Dustin Hoffman, Jolie and the rest of the cast as DreamWorks’ Jeffrey Katzenberg presented a check for $1 million to the Conservation International, in support of their efforts for the preservation of pandas in their natural habitat.
