Known For: Face of Calvin Klein for 20 years

Turlington repped Calvin Klein from 1987 to 2007—that's 20 years of looking absolutely perfect. But the model isn't just a hot body in tight jeans. After her documentary, No Woman, No Cry—about maternal mortality in Tanzania, Bangladesh, Guatemala, and the United States—was completed, she founded Every Mother Counts to increase education and reduce maternal mortality around the world.
