Just an observation, but it really is true that women are ageing much better now. Many of these 40+ women are much better looking than their 20 year old counterparts. Or maybe it's just that I'm getting older...
The list would be easier if it was which ones I wouldn't. They're all like 40+ now, heck Jessica Biel is like 38!
Jessica Claire Biel (born March 3, 1982) Yeah, not 'quite' 38 just yet. For me it's easily Monica Belluci. No one else even comes close. I've had a crush on her since The Matrix 2.
I'd say Jennifer Aniston and Cate Blanchett for me. If I had energy left in me, I'd give Madonna a try.
