According to Life & Style's Scene Queen, Brad Pitt smokes behind Angelina Jolie's back. He has difficulties to stop this habit.
One source said, "Smoking cigarettes is something Brad has done for many, many years and he smoked when he was married to Jennifer Aniston. It is one of the very few things he still does once in a while that he once did with his ex-wife."
"Angie allows the smoking as long as it really doesn't affect her or the kids, but she doesn't love it. Brad never smokes around the children and keeps it far away from his family, but it's a habit he still enjoys occasionally."
