Angelina Jolie and Brad Pitt are planning to adopt a fourth child from Africa, according to British newspaper reports.
The Daily Mail claims the Mr & Mrs Smith co-stars are hoping to adopt a baby girl from Ethiopia - the same country they adopted two-year-old Zahara Marley from in 2005.
The couple are also adoptive parents to Cambodian-born Maddox, five; Vietnam-born Pax Thien, three; and biological parents to 15-month-old Shiloh Nouvel.
When they adopted Pax Thien earlier this year, Jolie admitted they chose a boy from south east Asian country so Maddox could see the physical similarities between them, and hoped to find another African child for Zahara to identify with.
The Mail reports Jolie and Pitt will return to Ethiopia in November to seek another sibling for their expanding brood.
A source says: "Brad and Angie have made no secret of the fact that they are keen to extend their rainbow family. But they've always been very careful to ensure that they leave enough time between kids so that each child fully integrates into the family and feels truly settled.
"Angie in particular feels very strongly that while Shiloh will grow up seeing her family resemblance between herself and her natural parents, and Maddox and Pax will feel a connection between their birthplaces, Zahara has no such close-knit bond."
