Kelly Monaco in the days before her soap opera career. (1996-97 era)
She was about 20 then. She is now 42. According to her Wikipedia page, she is 5’3′, 95 lbs. That’s thin.
Found by accident while trying to see if she was really that tiny: I love this pic of her adjusting her bikini. I never did reach any conclusion about whether she really weighs 95 lbs, but some of the past images of her indicate that she may have gone down that low at some points in her life.
