Fifty-three years young, well, fifty-three years old, but boobtastic still brand spanking young and, well, if you're going to invest in a brand new pair, why not show them off. Apparently, Sharon Stone quite agrees, hitting the L.A. nightclub scene in a full on see-through top that flashed her bare silicon/saline melons for all the world to ogle. Hey, that's basic instinct too. I'm not sure what the plan is for the 60th birthday party, but, for now, enjoy 53.
