PEOPLE magazine has announced that Brad Pitt and Angelina Jolie will in fact adopt another child. It will make four children for the Hollywood couple and the third adoption for the Celebrity Orphanage.

For months the couple have been preparing to find a sibling for Maddox, 5, Zahara, 2, and 10-month-old Shiloh, a “process that began shortly after Shiloh was born [in May],” a source tells PEOPLE in its new issue.

It wasn’t until March 2 that a Vietnamese official revealed that Jolie, 31, had filed preliminary papers to adopt a child – according to one adoption worker, “a boy between the ages of 3 and 5.”
Why Vietnam? Jolie has traveled extensively in Southeast Asia and has visited the country at least twice. After adopting Maddox from Cambodia and Zahara from Ethiopia, she mused to Good Morning America in December that it might be a good idea to “balance the races so there’s another African person in the house for Z [and] another Asian person in the house for Mad.”

(Vu Duc Long, the head of the country’s international adoption department, told the Associated Press on Wednesday that the boy is between the ages of 3 and 4 and from the Tam Binh orphanage on the outskirts of Ho Chi Minh City.)

How high will they go? Add another nanny to their payroll. The addition will make a total of two groomsmen and two bridesmaids if Brad and Angie ever take the plunge. What happens to the kids and their psyche when Bradgelina splits?
