They both love their four children - but how do they feel about each other?

While she shoots her latest film Wanted in Prague, Angelina Jolie and Brad Pitt have set up home in the Czech capital.

Their four children – Maddox, five, Pax Thien, three, Zahara, two and Shiloh, one, must be quite a handful but Angelina is said to be already planning the adoption of another child.

Brad, 43, is undoubtedly devoted to the kids but is he getting fed up with Ang’s constant shopping for new tots?

‘I look at my kids and know they will inherit this world,’ he says. I’ want to do all I can to throw our weight in and make it a little better.’

But in Cannes this week, the couple looked less than joyful.

Angelina, 31, is reported to have blurted out to one interviewer who asked about their relationship: ‘So many parents today do separate and they still have a commitment to the children.’

And a source tells the Daily Mail: ‘If they look unhappy it is because they are.’
