LOS ANGELES – You know what they say about sucking cock. Do it once. The same now applies to Kristi Frank who joins a short list of individuals whose porn pasts have been outed thanks to appearances on mainstream TV. Along with Frenchie Davis from American Idol, Sara Kozer was the most recent whose presence on Joe Millionaire sparked an international beaver hunt in which it was revealed that Kozar had done bondage and foot fetish videos.

Now it turns out that Frank, who appeared on NBC’s The Apprentice Thursday night in which contestants vie to work for Donald Trump for a year, has done some T&A movies, notably in Zalmon King’s Red Shoe Diaries and an episode titled Swimming Naked. One might presume from all the furor is that Frank who sold lemonade on The Apprentice, was the one swimming naked in a scenario that has her playing a lifeguard who seduces an Olympic swimmer.

According to NBC publicity, Frank, 30, is the owner of two residential properties on the beach in Santa Monica, CA and the co-owner of the trendy restaurant. Her past as a Lake Tahoe blackjack dealer is discussed, but no mention is made of her, ahem, acting career.
