Celebrity Angelina Jolie has began chain smoking because of pressure amidst her divorce conflict with celebrity Brad Pitt.According to some source, despite getting operations to prevent cancer, the “Maleficent” performer is “smoking like a chimney”, reports aceshowbiz.com. “Angie doesn’t eat, she chain smokes. She easily goes through two packs a day. Going up against Brad has been the hardest thing Angie has ever faced. She’s stressed out and in a constant state of anxiety,” the source said.”The cigarettes kill her appetite, but she’s already skin and bones. The last thing she should be doing is skipping meals,” the source added.Earlier, there were reports that Jolie and Pitt might reunite for Thanksgiving after their six children kept begging them to spend the holiday together but later the plan did not work out.
