U.S. swimmer Amanda Beard appeared in Playboy in July of 2007, but with the Olympics back and everywhere, but it seems that people are googling her more for that then swimming. Links to photos below.

Her modeling work has included appearances in FHM, the 2006 Sports Illustrated Swimsuit Edition, and she posed unclad for the July 2007 issue of Playboy magazine.[5] She is a spokeswoman for Defenders of Wildlife, and enjoys interior decorating. Both of her sisters, Leah and Taryn, are swimmers. Amanda placed eighth in the Toyota Grand Prix of Long Beach Celebrity car race in 2006.
