I think it's interesting to look at their dates of birth. I find men attractive who are about my age (I was born in 1961), and women who are ten or fifteen years older than me.
Vincent D'Onofrio (1959)
Adam Baldwin (1962)
Anthony Keidis (1962)
Susan Sarandon (1946)
Sigourney Weaver (1949)
Russell Crowe (1964)
Andy Lau (1961)
and three guys I found attractive when they were younger (ie more like the age I am now)
Michael Caine
Harrison Ford
Cary Grant
There are plenty others.
BTW, I don't have an alternative, but don't you hate the word 'celebrity'? Here is my other list. Five words I dislike.
In no particular order, but all for different reasons...
Celebrity
Golf
Crisps
Effectively
Intestine
ETA - hey, a general passing-on of either meme to anyone who reads this and wants to do it
