Angelina Jolie is puffing up a storm because she is so "stressed out" over her ongoing divorce and custody battle against Brad Pitt. Despite undergoing surgeries to avoid cancer, according to a source, the "Maleficent" actress is "smoking like a chimney."

"Angie doesn't eat, she chain-smokes. She easily goes through two packs a day," the source reveals, "Going up against Brad has been the hardest thing Angie's ever faced. She's stressed out, and in a constant state of anxiety."

The source tells Radar Online, "The cigarettes kill her appetite, but she's already skin and bones. The last thing she should be doing is skipping meals!"

Recent report said that Angie and Brad might be reuniting on Thanksgiving after their six children kept begging them to spend the holiday together. The "Wanted (2008)" actress reportedly called her estranged husband and invited him over for a family holiday dinner. Brad said he would be bringing the turkey as he "want[ed] the kids to feel like it's the old days, like they're a family again."

A source close to the former lovers, however, denied Brangelina would have a reunion on Thanksgiving as he wasn't even invited.
