Karissa Shannon, if you need reminding, is the Playboy Playmate that was dating Playboy’s jurassic founder Hugh Hefner.

TMZ.com reports that Spencer Pratt was packing and moving stuff out of the home her shared with Heidi and discovered the video of Karissa Shannon and Heidi.

How fortuitous!

Before you get too excited about the idea of a Karissa Shannon, Heidi Montag sex tape, be warned that while Karissa says the tape does exist, she doesn’t think Spencer has it… and will sue him if he ever tries to release it.

Antwuan Cook’s wife, Paula Cook, filed court documents last week saying that Fantasia had an an affair with her husband and the pair made a sex tape. She said Fantasia and Antwuan met at a T-Mobile store and started their affair in August 2009.

Mrs. Cook says in the documents: “Throughout the course of their adulterous affair … Defendant/Husband and Ms. Barrino have at times recorded their illicit activity.”

Paula Cook is seeking custody of their children.

Fantasia also reportedly left a message for Mrs. Cook, saying, “He don’t want you. Maybe the next time that you get a husband you’ll know how to keep him. That’s why he is here with me.”

Danielle Staub is one of the stars of The Real Housewives of New Jersey – just the latest sorta-kinda celebrity whose sex tape is making headlines.

Hustler’s Danielle Staub Raw website includes the trailer for her sex tape video, with a preview of Staub in all her glory, and the site claiming it’s footage “she doesn’t want you to see.”

All in all, we’re not sure who will be paying to see the full NSFW Danielle Staub sextape… she’s a lot more scary than sexy.

Watch Kendra Wilkinson discuss the sex tape “Kendra Exposed” on the upcoming finale of her E! reality show finale.

Kendra says during an interview on her reality show: “It bothers me because people are going to judge me and stuff. I just hope to God nobody looks at me like a porn star. I just hope they don’t press play because that’s not me. I mean, that was me, but that’s not me now.”

New York Daily News is reporting that pre-orders for Kendra’s sex tape are the most of any release in Vivid Entertainment’s history.

Kendra Wilkinson’s sex tape is said to be released by Vivid Entertainment, the same company that brought you Kim Kardashian’s sexcapades.

Wilkinson’s reps tell OK! Magazine: “Kendra’s attorneys are currently evaluating and pursuing Kendra’s rights with respect to the purported video and any third parties involved in the possible sale, reproduction or distribution of the same.”

Steven Hirsch, founder/co-chairman of Vivid commented, “We know that Kendra has millions of fans and we feel that it’s rare to find well-produced, hardcore footage of a star of her magnitude. The tape was brought to us by a third party and after consulting with our attorneys, we are confident in our right to distribute it. We’ve been trying to reach Kendra but have so far been unsuccessful. We therefore made the decision to release ‘Kendra Exposed’ to stores across the country by the end of May.”

Kendra Exposed was made before Wilkinson moved into the Playboy mansion and became part of “The Girls Next Door,” and well before she met now-husband Hank Baskett.

Kendra’s rep said that “During this difficult time, Kendra and her family would greatly appreciate the respect of their privacy.”

Despite the request for privacy, Kendra is reportedly going to include mention of it on her reality series.

Turn off the cameras during sexy time, folks.

Chelsea Handler explains that the X-rated video was a joke, part of an audition tape that she would submit to comedy clubs.

Apparently the sex tape starts with Handler doing stand up, then a Chelsea sex scene… and back to more stand up.

Handler explained on Chelsea Lately (April 28 video above): “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. 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 fucking years!”

But is the Mindy McCready sex tape approved by the singer? Vivid Entertainment set an April 19 release date for the sex tape and no lawsuit has been filed by McCready.

Also, McCready apparently provides narration during the video about her affairs with Alan Jackson, Dean Cain and Roger Clemens.

Sounds like she’s fully on board and collecting a paycheck off of the sex tape.

The Carrie Prejean sex tape video came into play during Prejean’s settlement negotiations with Miss California USA Pageant officials (she was looking to gain more than a million dollars).

The lawyer for the pageant showed the Carrie Prejean video, a solo act of Prejean, well… you know… and voila! Prejean walked away from the negotiations with nothing from the settlement.

TMZ.com apparently had the video some months ago, calling it “extremely graphic” and choosing not to post it because “it was so racy.”

Carrie Prejean’s tell-all book will be available next week. Doesn’t everyone have a book these days??

TMZ.com is reporting that the Chyler Leigh sex tape is a fake due to the absence of a very large lower back tatoo. The woman in the sex tape has no back tatoo (and Chyler Leigh has had the tat since she was 19).

Additionally, the woman in the sex tape has a tongue ring, while Chyler Leigh does not.

According to Kristin Davis’ spokesperson: “This is not a photo of Kristin Davis. There is no sex tape.”

So there you have it.
