Angelina Jolie has adopted an Ethiopian baby girl orphaned by AIDS. She will complete the formalities of the adoption yesterday and will name her new daughter Zahara Marley.

Jolie, who spends much of her time touring the world as a goodwill ambition for the United Nations, is unwilling to reveal more details but she says she and her adopted Cambodian son Maddox, three, are "very happy to have a new addition to our family."

She has made it clear that she remains a single mother, despite constant rumors of a relationship with Brad Pitt.
