Washington, Nov 12 (ANI): Hollywood couple Angelina Jolie and Brad Pitt have revealed that they are keen to adopt a child from South America, but are being held back by the complicated adoption laws there.

They already - who already have three adopted children, Maddox, seven, from Cambodia, Pax, four, from Vietnam, and Zahara, three, from Ethiopia, and three biological children Shiloh, two, and baby twins Knox and Vivienne - are eager to add another child to their already huge brood.

Jolie had recently announced that the couple would be ready to adopt another child from abroad as soon as the twins turned six months old, and that they had started looking into which part of the world the child would come from.

The actress, however, admits that they have already run into difficulties, especially with both of them being unmarried.

"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," Contatcmusic quoted her as saying.

"Some countries won't let you adopt a child if you already have a child of the same gender at home," she added. (ANI)
