6) Alessandra Ambrosio

Short Bio
Among the top-earning models in the world, Alessandra Ambrosio knew early on that she wanted to be a model, taking classes in her native Brazil for years before landing her first modeling job: the cover of the Brazilian Elle -- not a bad start.

Were it not for a certain Katherine Heigl, Alessandra Ambrosio would have been AskMen.com’s No. 1 Most Desirable Woman in 2008. Still, landing at No. 2 that year (and No. 6 the year before) testifies to the appreciation and esteem our readers have for this stunning South American supermodel.

Why She's No.6?

In the first part of December 2008, and for the eighth year in a row, Alessandra Ambrosio brought her Angel game to the Victoria’s Secret Fashion Show, igniting the catwalk with her unique look, a cross between the shy, doe-eyed ingenue and a woman on the verge of total world domination.

However, for Alessandra Ambrosio, this year differed considerably from all the years past -- just three months before walking the runway for Victoria's Secret, she had given birth to her first child.
