Karissa Shannon

Playmate Karissa Shannon and Sam Jones of Smallville / federal drug charges / Karissa sex tape fame are OVER, according to a stunning report.

According to TMZ, she did the dumping ... in duplicitous fashion!

Manipulating her man with a cruel bait-and-switch, she told Jones she needed to move back into the Playboy mansion "for professional reasons."

That's hilarious enough, but after he helped her pack up her stuff, she dropped the hammer, confessing she was actually moving in with her sister.

Oh yeah, and their relationship was over. It's been real, Sam Jones!

Coming on the heels of Crystal Harris bailing on their wedding at the last second, this marks the week for Hugh Hefner's former girlfriends.

Kristina Shannon, your move.

The celebrity sex tape. It's become as common as a Lindsay Lohan trip to rehab.

As has been the case ever since Paris Hilton experimented with a camera and a dream, 2010 was yet another year filled with aspiring amateur porn stars, all of whom used the power of their genitalia to make headlines and increase bank accounts.

Below, we present the first-ever THG Sex Tape Awards, handed out to the real, the rumored and the downright disgusting...

Most Despicable: The year kicked off with a rumor that John Edwards actually filmed a sexual encounter with Rielle Hunter. We scoffed at first, but it was then proven true. Horribly, depressingly, incomprehensibly true.

Most Likely to Involve Roses, Drama: Bachelor castoff Rozlyn Papa was kicked off the show for fondling a producer. No surprise that she likes it in front of a camera.

Least Clothed Use of Performance Enhancement Drugs: Mindy McCready, Baseball Mistress.

Really, there's not a lot to add to this pic of Karissa Shannon and Sam Jones III, her boyfriend and sex tape partner, enjoying wholesome, festive fall activities.

With the Karissa Shannon sex tape due out any day now, the two of them gave us a preview of sorts, albeit by accident. You don't pose like this on purpose.

Or maybe you do, if you're a poor woman's Heidi Montag ...

Playboy model / sex tape star Karissa Shannon celebrated her 21st birthday yesterday with a champagne-soaked party in NYC. The co-guest of honor at the bash?

Twin sister Kristina Shannon, of course!

Karissa looked so delighted when boyfriend Sam Jones III gave a pair of Louboutins which cost $1,495 - he forgot to take the price tag off, what are the odds?

With proceeds from the Karissa Shannon sex tape, Sam can afford all sorts of fancy gifts for his girl, who became a D-list name in 2008, thanks to Hugh Hefner.

The twins were two of Hef's three hoes for a bit. Yet despite the "girlfriend" status, Karissa claims the relationship was "more for fun" and the chance to be on TV.

Wow, you mean a couple of 19-year-old twins weren't just itching for the chance to double-team an octogenarian? Shocker. Anyway, happy birthday girls!

Photos from the Karissa Shannon sex tape have just been released, and we're getting the distinct impression that we're dealing with a dirty, dirty individual.

No, really, she's in the tub a lot.

As such, there's no actual sex depicted in the promotional pics from the tape we've posted here. Unless Sam Jones III can hold his breath a long ass time.

The pair signed a deal to release the sex tape this weekend. Vivid is hyping it as a potential best-seller. Think that's legit? Peep these photos and see ...

Sam Jones III and Karissa Shannon are releasing their sex tape. It was only a matter of time. It only took a little of that, and cash, for the boning to go public.

Sources close to the couple tell TMZ that they both agreed to sell the Karissa Shannon sex tape to Vivid Entertainment when the offer hit the "six-figure range."

Unfortunately, footage of Heidi Montag is not included.

Vivid President Steven Hirsch says, "We are excited to finally distribute this amazing DVD. Not only is this extremely kinky for a celebrity sex tape, Karissa is absolutely beautiful. And as for Sam, let's just say he's no Smallville."

"This tape is sure to be one of our all-time best sellers."

Sounds like a challenge, Kim K. Got a sequel in you?

So much for that feigned anger and embarrassment.

It looks like Karissa Shannon may have had a change of heart when it comes to fighting the release of her sex tape, meeting yesterday with Vivid Entertainment execs.

Sam Jones III, boyfriend and Karissa Shannon sex tape partner, met with Vivid boss Steve Hirsch personally Wednesday. Probably to express their "outrage" over this.

Confronted by TMZ, Sam said the pair, which dubiously claimed they didn't know how the tape got out, is "exploring all of our options" ... then quickly covered his a$$.

"Especially our legal options," he said.

The bottom line: If they don't want the public to see Sam go to town on Karissa with whips and handcuffs, there's no way Vivid can sell it without their consent. None.

Any implication that they're the victims is absurd. Like Heidi Montag, they can put the kibosh on it if they choose. If it's released, they did it for the money. A lot of it.

A Karissa Shannon sex tape doesn't merely exist, as confirmed by the former Playboy model herself.

But the video is the most extreme Steven Hirsch has ever seen, and this is a man who knows his sex tapes! He's the chairman of Vivid Entertainment, the adult movie company for celebrities seeking attention.

Why is Karissa Shannon smiling? She's about to be a millionaire.

Hirsch spoke to TMZ last night and said of the taped pounding Sam Jones gives to girlfriend Shannon:

"[It's] definitely the most extreme video that I've ever seen, as a celebrity tape. There's everything you can imagine - whips, chains, handcuffs. It's absolutely crazy."

Wow. It's almost as if Karissa wanted such shenanigans to leak out in order to ratchet up the hype and make her the most money possible. But no way that could be the case, right?

Karissa Shannon is shocked and humiliated that a sex tape featuring her and boyfriend Sam Jones has been acquired by adult entertainment company Vivid.

And if you believe that, you probably also think Brad Pitt really cheated on Angelina Jolie with a French flight attendant.

In a joint statement, Jones and Shannon said Vivid was given the tape "without our knowledge or permission" and then the couple took the same route Kim Kardashian and so many others have taken before them, only to eventually settle for wads of cash, saying: "Our lawyers are on it and will be taking care of the situation."

Added Karissa:

Expect a Karissa Shannon sex tape to hit the market before the year is over.

Vivid Entertainment President Steve Hirsch has confirmed he's in possession of a video that features the former Playmate getting it on with boyfriend Sam Jones III. He describes the action as "extremely erotic" and says "a reputable third party" dropped the tape off in his office.

That's the first time Spencer Pratt has ever been referred to as "reputable."

Hirsch says he's "very impressed with the quality and content" of the tape. In other words: Shannon gets seriously naked and frisky in it!

Naturally, Karissa has claimed she wants the video back, and Jones said of Vivid's acquisition:
