Heidi Klum's Style Evolution: From Victoria's Secret Angel To Model Mogul (PHOTOS)

Heidi Klum's foray into modeling may have been on a whim, when at 18 years old she sent Polaroids of herself to a German magazine; however, her faith and indefatigable work ethic has lead to multi-platform fame. After kicking off her career in Europe, the fresh-faced beauty moved stateside, scored the cover of Sports Illustrated's swimsuit issue in 1998 and earned her wings as a Victoria's Secret Angel.

As Heidi boldly bares all in ad campaigns and on the runway, she also brings this same sense of self-confidence to the red carpet. From thigh-skimming mini dresses to bump-baring gowns, the "Project Runway" host and mother of four's enviable figure is something we all aspire to as we head into bikini season.

In celebration of Heidi's 39th birthday on June 1st, we're taking a look back at the supermodel's stem-baring style over the years, including adorable Ken and Barbie-esque moments with ex Seal. Vote on all her looks in the slideshow below.
