Cate Blanchett and Andre Upton adopt baby girl

EXCLUSIVE: Cate Blanchett adopts baby girl

Cate Blanchett and her husband Andrew Upton have added to their family and adopted a baby girl.

EXCLUSIVE: Australia's queen of the screen Cate Blanchett has adopted a baby girl.

This week the Oscar-winning actress has been arriving to collect her sons from their primary school in Sydney, snuggling a newborn to her chest.

The little girl is named Edith Vivian Patricia Upton.

On Saturday Cate's husband, theatre producer, Andrew Upton, told media the family are deliriously happy with the new addition.

"We're Thrilled," Andrew reportedly told The Daily Telegraph.

The couple already have three children – all boys – Dashiell, 13, Roman, 10 and Ignatius, six. Cate has spoken previously in interviews about her desire for a fourth child.

The family have recently announced they will be relocating to the United States, after her husband's term as artistic director at the Sydney Theatre Company ends in 2015. But Australia is close to their hearts, so they have vowed to return here at a later point.

Cate clearly treasures her family and is regularly seen on the school run, collecting her two youngest boys from primary school, while her oldest is already at high school.

Life with three boys has at times left Cate feeling "a bit demented" as she told W magazine.

But at the time she was quick to add that "the chaos of it is great." So great, in fact, the couple weren't ruling out a fourth child.

"Everyone says, 'Oh, you must have [been trying] to have a girl,'" Cate says. "If the next one was a boy, then that's just our lot!"

Adopting a baby has proved great joy to many high-profile couples, including Angelina Jolie and Brad Pitt, Deborra-lee Furness and Hugh Jackman and Madonna.

Recently, the Federal Government announced plans to examine adoption laws in Australia to make it easier for families to adopt babies from both here and overseas.
