Heidi Klum

Before gracing the cover of Sports Illustrated's swimsuit issue and sporting lingerie for Victoria's Secret, Heidi Klum was an undiscovered stunner from the small West German city of Bergisch Gladbach.

While still in high school, Klum won a modeling competition that launched her career in Europe. In the '90s, she went on to conquer the American market beside Tyra Banks, and eventually expanded her portfolio as the host, judge and producer of Project Runway and launched her own fragrance, jewelry and clothing lines. In 2008, Klum was nominated for the first-ever best reality show host Emmy, and along with her fellow nominees hosted the ceremony.

Klum, who was previously married to Ric Pipino and had a daughter with Italian entrepreneur Flavio Briatore, has since married singer Seal, with whom she's welcomed three more children.
