If you’ve bedded nearly 5,000 women, like Gene Simmons claims, the chances of probability mean that a sex tape is bound to emerge eventually.

KISS frontman Gene Simmons has two children with his longtime companion, Playboy model Shannon Tweed. But if a new sex video on genessecret.com is to be believed, Tweed isn't the only woman sharing Simmons' bed. The site shows video of Simmons engaging sexually with a blond woman called "Elsa," identified as an Austrian model. The sex video is likely to provide ample fodder for Simmons' and Tweed's reality series, "Gene Simmons' Family Jewels."

With the sex video, Simmons joins an increasingly less-than-exclusive club of stars to have participated in extracurricular activities in front of the camera.
