Famous? No second thoughts. Kristin Kreuk.
I have a huge, original high-quality photo of her on my desk. Half-dutch, half-chinese, all heavenly, baby. Oh, and she played Snow White as a role once. Definitely fairest of them all.
Runner ups:
Mika Nakashima
Jennifer Love Hewiit (In The Tuxedo? With glasses? SWOON. It hit ALL my hot buttons)
And then the other is not famous and you would not know her. <3
