The following story should come as no shock since I had one porn star admit to me a few years ago that she fucked Howard Stern after he interviewed her on air. Or so she claimed.

New York- Howard Stern might want to disinfect his microphone.

The potty-mouthed germophobe can't be too happy to hear that porn stars Ron Jeremy and Tabitha Stevens are saying they made a sex video in Stern's studio after hours.

Word is that about three years ago, Stern regular Crazy Cabbie proposed the idea to the Hedgehog, who brought in a film crew and a cast that included Stevens and the band Alien Ant Farm.

"We went in late at night," Stevens told us. "They shot a lot of it right in Howard's studio. My scenes were in the green room."

Stevens says Cabbie told the cast Stern had sanctioned the video, though, in fact, "Howard had no idea." An annoyed Stern pressured Cabbie to get Jeremy to surrender the tape, Stevens said.

But Jeremy told Steppin' Out editor Chaunce Hayden he kept a copy and hopes to release it someday.

"Ron is proud of his work," said Hayden.
