The hot-blooded stars on E!’s Kill Reality series are supposed to be filming a horror movie, but the scenes backstage may be more fitting for a triple-X booth. While their on-screen debauchery has already earned the series impressive ratings, a source close to the show claims the real reality action took place at the stars’ communal Malibu beach house.

“The whole cast was drunk or wasted throughout the taping, and everyone was having sex with everyone else,” says the insider. “Not only were there orgies, but at one point someone relieved himself on Trishelle [Canatella, of Real World: Las Vegas and Playboy fame] in full view of the cameras—and, from what I saw, she loved it.” In another booze-fueled bacchanal, we hear Tonya Cooley, the lusty blonde of Real World: Chicago fame, begged co-stars to do lines off her genitals “because it turns her on.”

On a more romantic note, true love somehow managed to blossom between the strung-out participants. While viewers might be charmed by Survivor reject and internet porn star Jenna Lewis’s none-too-shy courtship of Real World: Las Vegas alum Steven Hill, we hear the relationship on everyone’s lips was the one between Kill Reality’s only gay star, Reichen Lehmkuhl of The Amazing Race 4, and American Idol’s Clay Aiken. While Aiken never appeared at the house, we hear Lehmkuhl was constantly taking calls from the pixie-like singer.

“Reichen swears there’s nothing going on,” says our source. “But Clay kept calling non-stop. It was all very weird.”

Though much of the show’s footage is too raunchy to make it onto the small screen, the show’s producers are apparently compiling an outtake reel of the kinkiest moments. “Other than the bathroom, every room was filmed, so there’s some really good stuff,” says the source, who hinted that the hottest material will find its way onto the internet sooner or later.

The show’s publicist, Elizabeth Johnson, confirmed that there were many “drunken hookups” between the cast members, but said she couldn’t discuss the lewdest events because she wasn’t present during the taping. As for Aiken’s telephone calls to the set, Johnson said, “I don’t really want to get into that.” A spokesman for Aiken couldn’t be reached for comment.
