Vietnamese vixen Navia Nguyen grew up in New York City and moved to London, where she was spotted by a photographer. That led to her scantily clad appearance in the Sports Illustrated Swimsuit Issue in 1997. She was the first Asian model to grace those sexy pages. For a more revealing look at her Viet Congs, check out The Boys & Girls Guide to Getting Down (2006). While she doesn't show her down unders, her tiny top makes a nice shelf for a guy to snort coke off of. You'll get high without the use of pharmaceuticals.
