Angelina Jolie with son MaddoxAngelina Jolie with son MaddoxSuddenly Angelina Jolie's trip to the baby department of Harrods last week makes sense.

The 30-year-old actress is about to become a mother again... but to an adopted daughter.

Angelina, along with best pal Brad Pitt and her son Maddox, are currently in Ethiopia sorting out the final bits of paperwork before they bring the little bundle home.

The actress picked out the little girl after Maddox blew her a kiss - she's a five-month-old Aids orphan from Addis Ababa.

"We're very happy to have a new addition to our family," Angelina revealed.

"My son is in love with Africa, so he has been asking for an African brother or sister."

A nurse from the orphanage where Zahara was living told The Sun: "The baby looks very like Angelina. They have the same colour eyes. Angelina told me, 'She is very beautiful and I will cherish her'."

Angelina, who adopted Maddox three years ago from a Cambodian orphanage, had previously revealed that she wanted to adopt again.

"I want to create a rainbow family. That's children of different religions and cultures, from different countries," she said.

"I believe I'm meant to find my children in the world somewhere and not necessarily have them genetically.

"I like to think with every adoption I'm saving another child from an orphanage."

Although Brad has been with Angelina throughout Zahara's adoption process, he is not named as the adoptive father and the pair still deny that their relationship is anything more than platonic.

They had been spotted shopping for cots and baby clothes in Harrods last week - prompting rumours that Angelina was pregnant with Brad's child.

She denied the reports during her appearance at the Live 8 event at Cornwall's Eden Project over the weekend.
