Adult entertainment company Vivid, which specialises in X-rated celebrity "movies", has made a name-your-price offer for proof of the sex sessions.
Chairman Steven Hirsch said, "Our offer is to any woman who has proof she was a paramour of Tiger Woods and will sign a contract with the studio. Of course we would need proof that a relationship actually took place.
"Tiger Woods is an American sports legend and we feel there would be strong public interest in an intimate look at him through the eyes of one of his lovers."
A Stateside source said, "Tiger's biggest fear is that he's been set up by one of these women and that they have a sex tape of him.
"He knows for sure that there could be no way back for him then.
"He still faces other women coming forward, and the prospect of Rachel Uchitel selling her lurid story."
Besides cocktail waitress Jaimee Grubbs, New York socialite Rachel Uchitel (34) and Vegas nightclub executive Kalika Moquin (27) are said to have had affairs with the golfer.
