Some believe that frequent smoking helps her to remain always skinny. Last years Keira was seen smoking inside many public places such as bars and restaurants, and in some cases she was asked to go outside to smoke!
She admits she has at least one bad habit and by this is meant smoking, of course.
Though she says she smokes rarely, this habit has nothing to do with her commitment to healthy lifestyle.
The 35-year-old actress prefers to hide from public her smoking habit, but professional paparazzi like to catch her with a cigarette.
During her pregnancy she refused from smoking and told she plans to get rid of it for good. However, after that she was seen smoking again.
But soon she was caught smoking, in spite doctor's recommendations.
