Smoker?
first of all, I recently saw the episode of the simpsons (not the one Kathleen actually did provide her voice but) making fun of her voice.
secondly, I just saw the Nip Tuck episode which she appeared.
doctors saying she really has a smoker's skin.
to me, her voice in nowdays sounds like Italian-American mafia.
She was a heavy smoker for decades and recently quit or still doing... That won't be a surprise.
the opposite way will be very shocking.
