Wearing a stunning black strapless dress and accompanied by her husband Brad Pitt, Angelina looked gorgious on the red carpet for premiere of her movie "Changeling," a 1920's thriller directed by Clint Eastwood.

The premiere also marks the first time the actress has been in the United States since giving birth.

Jolie plays a mother, whose 9-year-old son is kidnapped in Eastwood's 1920s-based drama. Jolie said, "Your worst fear is anything happening to your kids. The reason I didn't want to do the film for a long time…every day I came home, and I was so clinging to my kids. I was grabbing them. And checking them in the night. It scares me."

The proud mom said her older kids Maddox, 7, Pax, 4, Zahara, 3, and Shiloh, 2, like doting on the twins.

Angelina told People that looking after a brood of six was taking its toll. "We are a little bit (sleep deprived). We have some help a couple of nights a week, so on those nights we catch up on our sleep."

When asked if she would consider adopting another child, Jolie told reporters: "We're going to have more kids one way or another."
