Brad Pitt and Angelina Jolie are planning to adopt another child.

The couple — who have adopted children Maddox, seven, Pax, four and Zahara, three, as well as two-year-old biological daughter Shiloh and two-month-old twins Knox Leon and Vivienne Marcheline — are considering raising a child from either Namibia, Bolivia or Paraguay.

The pair are said to be interested in giving a child from Namibia a home as Shiloh was born in the country.

However, Jolie is keen to adopt from a South American country because she wants to raise awareness of the large number of children who are in need of help in the region.

Meanwhile, Jolie and the children recently joined Pitt in Berlin, where he is filming Quentin Tarantino's new film.

The family are reportedly staying in a 12 000 sq ft villa — which they are leasing for $40 000 per week — on the outskirts of the German city. The property was also inhabited by Tom Cruise while he was filming 'Valkyrie'.
