A tape showing Kiss star Gene Simmons having sexual relations with a model has been posted on the Internet.

Simmons allegedly made the tape while carrying out promotional duties as a spokesman for Frank's Energy Drink. Website AVN.com is selling the recording to users who want to download the footage.

According to the site, the woman in the film is not Simmons' girlfriend, Shannon Tweed. She has been identified as a model named Elsa, who reportedly works for the drinks company the star was hired to promote.
