Pitt and Jolie to adopt another child

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.

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.
