Angelina Jolie and Brad Pitt are keen to adopting a child from South America - but they are finding it difficult to negotiate the complicated adoption laws. The couple already have three adopted children, Maddox, seven, from Cambodia, Pax, four, from Vietnam, and Zahara, three, from Ethiopia. They also have three biological children Shiloh, two, and baby twins Knox and Vivienne.

Jolie recently announced that the couple will be ready to adopt another child from abroad as soon as the twins are six months old.

And the couple is already looking into which part of the world they want their next family addition to come from. But the actress admits that they have already run into difficulties.

Jolie says, "We've thought about South or Latin America, but it's very complicated. Brad and I aren't married, so, as a technically single woman, there are lots of countries I can't adopt from. And, as a technically single man, most countries wouldn't allow Brad to adopt at all. Some countries won't let you adopt a child if you already have a child of the same gender at home."
