Stephen Hawking certainly has discovered some new heavenly bodies — at a California jiggle joint.

The apparently sex-crazed 70-year-old genius astrophysicist, who is confined to a wheelchair by Lou Gehrig’s disease and uses a computer to speak, has been spotted several times getting lap dances at California sex club Devore, RadarOnline reported today.

Hawking, whose work on black holes earned him international acclaim, arrives at the club with an entourage of nurses and assistants and has “naked women grind on him,” RadarOnline reported.

“I have seen Stephen Hawking at the club more than a handful of times,” the source told the online celebrity gossip site. “Last time I saw him he was in the back ‘play area’ laying on a bed fully clothed with two naked women gyrating all over him.”

Although debilitated by the disease, which is also known as motor neurone disease, Hawking has been a member of the Freedom Acres swingers club for more than a decade, according to the report.

Hawking and his second wife, Elaine, divorced in 2006. His first marriage, to Jane Hawking, ended in 1990.

Diagnosed at the age of 21, Hawking was given only a few years to live but has defied medical opinion by reaching his eighth decade.

“I’m sure my disability has a bearing on why I’m well known,” he once said. “People are fascinated by the contrast between my very limited physical powers, and the vast nature of the universe I deal with.”

Much of his work has centered on bringing together relativity (the nature of space and time) and quantum theory (how the smallest particles in the universe behave) to explain the creation of the universe and how it is governed.

Hawking is a good sport, according to RadarOnline, and will even pose for photos with fans as long as the pics are taken in “a neutral area.”

“Real Housewives of Orange County” star Vicki Gunvalson’s ex-husband Donn has also been spotted in the Southern California swingers club, RadarOnline said.

“But Stephen is by far the last person I ever expected to see in this club,” the source told the site.
