As for actual women: SARAH BRIGHTMAN. How can you look that good at 49? (obviously with surgery, but they're unnoticeable)

Good call. In my personal top ten most beautiful, Mariska Hargitay, 45 years old. (all 10 of whom are equally beautiful including Jessica Alba, Kirsten Dunst, Meg Ryan, Heather Lockyear, Courtney Cox, Elizabeth Hurley, Kylie Minogue, Audrey Hepburn and a girl Helen, who I used to know.)

As far as men go, it's not that I want to turn gay for them: to have their bodies and looks instead of mine would be enough...
Harrison Ford,
Daniel Craig
Jet LI
Hugo Weaving (..he is just plain freaky looking. You could really have some fun with that!)

I don't know about Alba, but Hargitay, Meg Ryan and Courtney Cox are stunningly beautiful.

As for men... I'd really love to look like either Harrison Ford, Clive Owen or Hugh Jackman.
