Angelina Jolie opened up about her pregnancy with newborn twins Knox and Vivienne in a Los Angeles Times interview about her new movie, 'Changeling.'

"I got pregnant right in the middle of it and I think partially because of it," Jolie told the Times about filming the movie in which she played a woman whose son was abducted. "I was so emotional about children that I think something kicked into gear."

The mom of six with partner Brad Pitt told the Times that "the center of my life is my kids," and noted that being a mom isn't always easy: "I woke up at 3 in the morning with four kids with jet lag and two babies. I put myself together for a few hours and go out. And then I go home. This is my job."
