7. Jessica Alba

As a celeb who was never linked to scandalous behavior and controversy, Jessica Alba is surely one of the most surprising celebrity smokers on this list.

But Alba doesn’t always smoke with the same intensity. She’s been known to go from moderate to hard-core smoking, depending on the situation. Mostly it’s the former, but in certain events like trying to get rid of pregnancy weight Jessica Alba can smoke a pack in a day.

Similar to Keira Knightley, this actress also suffered anorexia in her teens, only to turn to smoking as a weight gain-prevention method once she got older.
