Well, what a tough question, but here we go:
Jennifer Love Hewitt, suprised no one has mentioned her yet
Anna Kournikova
Delta Goodrem, an Aussie singer (this is her before she got cancer, has shorter hair now but will hopefully grow it long again)
what do you guys think of Delta?
Tara Reid
and then Imogen Bailey
there is obviously plenty of others out there, but these are among the best for me.
