She may just be a "social smoker" (not that that's a good thing to be).
She used to be a regular on the Food Network - her husband is an Italian chef. Unfortunately, actors & actresses often have to smoke on screen (although, today, they offer people a non-tobacco product to use). And some do it to control weight.
That pic must be a “Goodfellas” reunion. She played Ray Liotta’s girlfriend in the last third of the movie.
