exactly--smoking 2-3 cigarettes a week with friends, while drinking, or out and about is not going to show up on the skin the way regular smoking (many cigarettes daily) is going to. She also obviously takes other precautions (healthy eating, exercise, skincare) to prevent premature aging.Even if she smokes...with skin like that, I doubt she smokes/parties nearly as much. At 30 it would show. I believe she's disciplined for most of the time, with the occasional vice. Atleast now, for sure even if it weren't like that when she was younger.
