Looks like six kids aren't enough for Brangelina.

Brad Pitt and Angelina Jolie are thinking about adopting another child from either Namibia (where their daughter Shiloh was born in May 2006) or from one of the more impoverished countries in Latin America, possibly Bolivia or Paraguay, a source tells the Chicago Sun-Times.

The focus on South America comes from Jolie's interest in drawing attention to the large number of desperately needy orphaned children in that region, the paper says.

Pitt and Jolie have six children: Maddox, 7, adopted from Cambodia; Pax, 4, adopted from Vietnam; Zahara, 3, adopted from Ethiopia; Shiloh, 2, who is their biological child and twins Knox and Vivienne, who are biological and who were born in July.

Brangelina is also considering a long-term lease on a very secluded villa in southern Spain — surrounded by many acres, like their rented estate in the south of France, the paper reports.
