Everyone knows these days that Angelina Jolie is all about the family.

So when she gets talking about her favourite topic - the Brangelina brood - there's just no stopping her.

She has doubled her kids since she hooked up with Brad Pitt - becoming pregnant with daughter Shiloh and then adopting their newest addition Pax Thien - but how did it all happen?

She told Reader's Digest: "Before I met Brad, I always said I was happy never to have a child biologically. He told me he hadn't given up that thought.

"Then, a few months after Z (adopted daughter Zahara) came home, I saw Brad with her and Mad, and I realised how much he loved him, that a biological child would not in any way be a threat. So I said, 'I want to try.'"

With such a house full it must be a struggle for Brangelina to have any, ahem, quality time:

"Right now, that's our problem! We hang out. We try to talk over the swing set. We'll have a date night once everybody is settled."

And just what does it for Brad?: "I could be dressed up in the sexiest outfit for a photo shoot, and by his behaviour, he'll let me know that's nice, but it's nothing as sexy as when I'm home surrounded by the kids or reading books, educating myself."
