Angelina Jolie says she's too busy to star in another film with partner Brad Pitt.

The Oscar-winning actress - who famously met and fell in love with the handsome actor on the set of 'Mr. and Mrs. Smith', while he was still married to Jennifer Aniston - thinks it would be fantastic to work with him again but doesn't have the time because they raise six children together.

She said: "I'd love to work with him but we have a lot of kids!"

Angelina says being parents to Maddox, eight, Pax, five, Zahara, four, Shiloh, three, and 15-month-old twins Knox and Vivienne is hard work as she and Brad try and make sure all their kids are happy and fulfilled.

She said: "We try to find a balance in our lives because we want to educate our children and fulfil our dreams as artists and as people. So before making a decision we think about it thoroughly because our family is our top priority. On a daily basis we make sure their schooling is going right and we're disciplining them properly and we're spending enough time with all of them individually."
