Angelina Jolie says her new film helped her get pregnant. The 33-year-old actress - who raises six children with partner Brad Pitt - believes she wouldn't have conceived twins Knox Leon and Vivienne Marcheline if she hadn't starred in new movie "Changeling," in which she plays a mother whose son goes missing.

She said: "I got pregnant right in the middle of shooting and I think partially because of the film. I was so emotional about children that I think something in me kicked into gear."

Angelina Jolie, on the Today show to promote her new film "Changeling," revealed plans to adopt another child. Speaking in an interview with Matt Lauer, she did not give an exact time frame as to when she'll adopt. But most importantly, she did not give any information about where she is planning to adopt.

When asked by Lauer about how soon she is planning to adopt another child, the 33-year-old actress said, "It depends. You can't adopt, you can't even start the process until any new children are 6 months old to understand how the new family has settled to see what you can absorb into your new family. I think that's a smart thing anyway to understand when it's the right time to bring another child in."
