Jolie Planning to Adopt Another Child

"Next, we'll adopt," Jolie tells CNN's Anderson Cooper in an interview to air Tuesday on "Anderson Cooper 360" (10 p.m. EDT).

Jolie, 31, gave birth to daughter Shiloh Nouvel Jolie-Pitt in Namibia last month. The couple have two older children, 16-month-old Zahara, adopted from Ethiopia, and 4-year-old Maddox, adopted from Cambodia.

"We don't know which _ which country. But we're looking at different countries," the actress tells Cooper. "And we're _ I'm just _ it's gonna be the balance of what would be best for Mad and for Z right now. It's, you know, another boy, another girl, which country, which race would fit best with the kids."

Both Maddox and Zahara's surnames have been legally changed to Jolie-Pitt after Pitt, 42, announced his intention to adopt the children.

The Jolie interview will air Tuesday as part of CNN's entire day of programming devoted to World Refugee Day.
