Angelina Jolie and Brad Pitt have reportedly adopted a new baby boy from a slum in Cambodia.

Whilst Angelia was directing ‘First They Killed My Father’ in northwest Cambodia, Angelina and Brad’s daughters Shiloh, nine, and Zahara, 10, formed a close friendship with a family with 13 children.

News.com.au reports that Angelia was so shocked by the family’s living conditions, that she vowed to sponsor the family and adopt their young son, Allouy Shoun.  The news outlet also reports that 40-year-old Angelina did not inform her actor husband Brad before making the decision.

“This was all staged like some secret military operation,” a source close to the couple told Radar Online. “Angie didn’t want Brad to get wind of what she was doing because she knew he’d throw a fit! Angie has pledged to pay more than $1 million to help support the family and to adopt baby Allouy.”

Since meeting the family, daughters Shiloh and Zahara are said to have spent almost $300 on items for them, including clothes, trips and two new bikes.

One of the children in the family, Leida Shoun, 16, explained:

“We only had one bicycle for the entire family and it was old. So for us this is an amazing gift. Shiloh and Zahara and their family are very good, very nice people!”

Speaking about the Jolie-Pitt family, she continued:

“We have known them for a while. They sponsor us. I play with Shiloh or Zahara. They meet us in Siem Reap town. They take us to the arcade in the Angkor Centre. I like it when we play ball.”

The Maleficent star adopted her first child Maddox, 14, from Cambodia in 2002, and subsequently adopted Zahara and Pax.  She also has children Shiloh, Knox Léon and Vivienne Marcheline with Brad.
