Anyway, in my opinion, Courtney Thorne-Smith, by far. This isn't to demean the beauty of Ms. Love Hewitt; but, I have always thought that Courtney Thorne-Smith was one of the most beautiful women in Hollywood. I think the first time I saw her was in the movie "Summer School" about 30+ years ago and I have been in "lust" ever since.
