"Chelsea's tape will never come out," a source close to the situation told RadarOnline.com.

The source said a combination of legal and financial reasons guarantee the tape will not hit the market.

Tila Tequila has built a career on her sex appeal, but the Shot At Love star recently took an ex-boyfriend to court in an attempt to stop him from releasing a sex tape and RadarOnline.com has the documents.

“Ten brought a digital video camera with us on the trip…some of what was filmed included the two of us engaged in intimate sexual relations,” Tila stated.

An unnamed porn actor has tested positive for HIV and the industry’s most famous face, Ron Jeremy, tells RadarOnline.com the buzz is that it’s a male actor who works in gay adult films.

“It’s politically incorrect to say, but it’s typically a lot easier to get it through homosexual intercourse than heterosexual,” Jeremy said in an exclusive interview with RadarOnline.com.

In the gay films they don’t necessarily get tested because they use rubbers all the time, unlike in the straight films. Gay film companies do not require testing because they use protection for everything.”

News of the infected actor broke Tuesday, prompting two of the industries leaders – Vivid Entertainment and Wicked Pictures – to shut down production.

This is the tape Tila Tequila doesn't want you to see, and only RadarOnline.com has it.

The homemade sex tape was shot back in 2004 with an ex-boyfriend before the Shot At Love star made it big on MySpace and MTV.

Tila went to court to file an injunction prohibiting the release of the sex tape, but a judge denied the motion on Thursday.

Chelsea Handler’s sex tape is very close to being sold and before its release RadarOnline.com can reveal new details about the video.

“After Radar broke the existence of Chelsea’s sex tape several people came forward with copies,” a source told RadarOnline.com.

“It’s been shopped around for the past four months and a deal is very close to being made.”

As RadarOnline.com previously reported, the VHS tape was made more than a decade ago after Chelsea moved to Los Angeles and was intended to be a demo of her stand-up routine and included a clip of her homemade sex tape.

Handler claims the demo-tape-accidentally-recorded-over-sex-tape theme was intentional and has dismissed the tape as a joke that she showed a birthday parties.

But the sex on the tape, which may be simulated, is graphic enough not only to shock but also to draw substantial interest in releasing the tape publicly.

“My name is Chelsea. I moved out here from New Jersey about two years ago because I wanted to be an actress,” Chelsea states at the beginning of the tape.

The video is too graphic to show on RadarOnline.com, which ends with Chelsea’s partner asking, “Did we get the (bleep) shot?”

After 15 seconds of sexually explicit footage the tape cuts back to Chelsea in the middle of her stand-up routine.

And whatever you think of the joke of sending out an audition tape that appears to have been accidentally recorded over a sex tape, the early-career standup routine does not get a lot of laughs.

After nearly eight minutes of an excruciatingly bad and drawn-out waitress joke the tape cuts to Chelsea’s bedroom where she’s naked on all fours having what appears to be sexual intercourse with a male partner who speaks with a British accent.

"I would like to say to RadarOnline.com, thanks for ruining my surprise Christmas gift to my staff, and number two, it was made as a joke,” Chelsea said on her show Chelsea Lately when RadarOnline.com initially broke the story.

“I put it on an audition tape for a comedy club, because I'm a comedienne, and I've been showing it at birthday parties for f**king years!"

But as RadarOnline.com exclusively reported, we have viewed the entire tape and that’s one XXX-rated joke! Chelsea is naked and the sex act is graphic enough.

RadarOnline.com confirmed that the tape was sent out to Hollywood agents as a demo when Chelsea was looking to secure work. If it was an attempt to get noticed, it worked!

“Chelsea gave this demo tape to a bunch of talent agents and managers hoping to book some gigs,” the source said.

“It was taken so long ago, distributed on old VHS tapes and the stand-up was so bad that most of the recipients of the tape probably didn’t even watch past the first couple of minutes and missed the sex tape part altogether.”
