The couple have three adopted children, six-year-old Maddox; Pax, four; Zahara, three along with 21-month-old daughter Shiloh, and are reportedly expecting twins.

They want their kids to live a normal life and indulge their junk food cravings.

A source close to the family told Life and Style Weekly magazine: "If Zahara wants ice cream for breakfast, she'll get it. They like to take care of the kids on their own. But they can't cook, so they look for food that comes out of a box and doesn't have to be cooked and the kids just love fried food.

"Brad and Angelina work really hard at letting their kids be normal. That means they let them do stuff we all did as kids, like eat chocolate or a bag of chips."

However, it was recently reported the children have been fighting over the calorific treats.
