Gilian Anderson Smokes...
The famed starlet of the X-Files is definitely an in real life smoker who does not have a problem with the sultry aspect of being a smoking celeb. I even remember a couple of scenes of her smoking in the X-files, nothing real long or outstanding but more than enough to convince me, anyway, that she is legit. There are also a ton of pics of her out there on the net and she has smoking scenes in several other movies.
