Tiegs, besides being a foxy supermodel and Sports Illustrated Swimsuit Edition staple, also helped turn the drowning company, Sears, around. Her own fashion line made nearly a billion dollars. Yeah, the girl in the pink bikini on the poster you found in your dad's stash helped save a department store and she's now saving the Earth by encouraging everyone to go green.
