Australia has produced a number of dominant swimmers.
However, Leroux chose to play for the American under-20 team in 2008 and has been a star for the national program ever since.
She appeared in the 2011 Sports Illustrated Swimsuit Issue and you can see why above.
She was also runner-up for Miss Universo Paraguay in 2006.
Long before Michael Phelps dominated the pool on the men's side, it was Ian Thorpe who was regarded as the best competitive swimmer in the world.
