[Uston]

or underpublicized:

Elizabeth Banks (she was in Seabiscuit, Spider-Man, and Catch Me If You Can as well as being in Ivy League grad)

Hunter Tylo (at the very least, the hottest 40 year old woman ever)

Jessica Alba

Piper Perabo

Natalie Gulbis (LPGA member, and, to my knowledge, she actually prefers men!)
