He may spend his days poring over advanced scientific theories, but Stephen Hawking reportedly has demonstrated interest in more carnal pursuits as well. It turns out the world-renowned physicist has frequented a swingers’ sex club in Southern California. Radar Online first reported that Hawking, 70, was spotted last week at the Freedom Acres sex club in Devore, Calif., where he arrived with a crew of nurses and assistants before paying for several naked babes to give him a private dance performance. A spokesman from Cambridge University downplayed Radar’s report, saying it’s completely untrue that Hawking is a “regular” at Freedom Acres. In the past, Hawking has been photographed with other happy patrons at London’s Stringfellows club.
