BRAD AND ANGELINA PLAN FOR BABY NO4; Couple ready to adopt again.

Byline: By MIRROR REPORTER

NEW parents Brad Pitt and Angelina Jolie are already planning their next baby.

Hollywood's hottest couple celebrated the birth of their daughter Shiloh three weeks ago and have two adopted children Maddox, four, and 16-month-old Zahara.

But they are so happy they are already planning to add to their growing family.

In her first interview since giving birth, Jolie, 31, admitted she and 42-year-old Pitt have already been researching countries from where they can adopt children.

Asked if they were planning to expand their family, Angelina insisted: "Yeah, yeah. Next we'll adopt."

They say their choice of country will in part be to compliment their children with Maddox, from Cambodia, and Zahara born in Ethiopia.

She added: "It's gonna be the balance of what would be the best for Mad and for Z right now. It's, you know, another boy, another girl, which country, which race would fit best with the kids."

Oscar-winner Jolie also admitted she was "terrified" during the birth of Shiloh, who was delivered by Caesarean section in Namibia.

In a US interview aired last night, she said: "You know, because you're there for the birth, which I wasn't for my first two kids, you're just suddenly terrified that they're not gonna take a first breath.

"That was my whole focus. I just wanted to hear her cry."

The UN goodwill ambassador, who donates a third of her income to charity, revealed Pitt was there throughout to support her, adding: "He was in the operating room."

With three failed marriages between them, the couple insisted they have no plans to wed and will instead share a commitment through their children after Pitt became Maddox and

Zahara's adoptive father in January.
