It's almost an even split between Amanda Beard and Natalie—both extremely attractive swimmers who could shark-like swim circles around you. Amanda snags a bit more press (and a higher ranking in this list) for her willingness to play the sexy card. Meanwhile, Natalie just keeps swimming and collecting medals; the bronze she just picked up in London is her 12th medal, which ties her with Jenny Thompson and Dara Torres for the most medals ever won by an American woman.
