Pregnant Angelina Jolie is struggling to carry her twins because the babies are so heavy. The Oscar-winning actress, who is rumoured to be expecting a boy and girl, is finding the burden of having two tots inside her exhausting. A source close to Angelina who already has three adopted children, Maddox, six, Pax, four, Zahara, three, as well as 22-month-old daughter Shiloh with partner Brad Pitt told America's Star magazine: "Her feet are so swollen that her shoes have gone up a half size at least. "She's constantly tired. She's sick and irritable and feels heavy and weak." Angelina is also said to be suffering from gestational diabetes, a condition in which women without previously diagnosed diabetes exhibit high blood glucose levels during pregnancy. An insider added: "Angelina has gestational diabetes. She found out about a month ago and has been trying to keep it under wraps. She's been seeing a nutritionist about it - frequently." She has now had to change her diet in order to cope with her condition. Her brother James Haven said: "She doesn't pay much attention to food. But it's different when she's pregnant."
