The romance between Melissa Rivers and porn king Steve Hirsch has officially come to an end.

Sources close to the former couple tell us the two recently called things off ... because they each had too much stuff going on in their personal lives to focus on a relationship.

We're told the split was mutual ... very amicable ... and the two are still friends.

TMZ broke the story ... Hirsch -- president of Vivid Entertainment -- began dating Rivers back in December after meeting through mutual friends.

Now that Melissa has dabbled in porn, the possibilities are now end-less.

Octomom's topless photo shoot didn't completely sabotage her porn future ... but it did drastically reduce her XXX market value -- this according to a brand new porn offer from Vivid Entertainment.

In case you didn't know, Vivid honcho Steve Hirsch offered Nadya Suleman $1 MILLION in 2009 to star in her own skin flick -- but Octo turned him down.

Hirsch made a second offer in 2010 to help bail her out of foreclosure -- $500,000 for ONE hardcore scene -- but Octo rejected that too.

Now, in the wake of Nadya's topless photo shoot, Hirsch is making one final push to lock the mother of 14 into a porn contract -- except this time ... he's not offering 7 figures ... OR half a million ... not even close.

Hirsch sent Octo a letter yesterday, offering her a paltry $100,000 to appear in THREE hardcore sex scenes -- claiming, "Regrettably your market value has diminished."

She might need the money, but don't count on Nadya chomping at the bit any time soon -- Octo called in to TMZ Live yesterday, and seemed pretty adamant she'd never do porn in a million billion years.

Count Linda Hogan among those who want to see Hulk Hogan's sex tape -- but get your mind out of the gutter ... it's because she thinks it will help her defense in Hulk's lawsuit against her. 

As TMZ first reported, a sex tape featuring the wrestling legend is being shopped to Vivid Entertainment ... a tape Hogan says was made without his knowledge. 

Sources close to Linda tell TMZ she'd like to get a look at the tape because she feels it could be a key piece of evidence in Hulk's defamation lawsuit against Linda. Hulk sued Linda last year ... claiming she was lying when, in her book, she alleged Hulk was abusive and cheated on her. 

We're told Linda would like to figure out when the tape was made because it could help her prove Hulk was a cheater. According to our sources, if Linda can figure out who has the tape, she'll attempt to subpoena them for her case.

Hulk told TMZ this week he has been faithful to his current wife Jennifer, so the tape is at least five years old.

The kingpin of porn has reached out to Hulk Hogan in an effort to entice him to change his mind about the sex tape that has surfaced featuring the famous wrestler.

Steven Hirsch from Vivid Entertainment has sent Hulk a letter, which touts his company's stable of stars who include Kim Kardashian, Kendra Wilkinson, Tommy Lee and Jimi Hendrix.

After we broke the story that Hulk is front and center in a videotaped sexual encounter with a mystery brunette, he was adamant that he had no idea he was being taped and he would go after the people behind the tape both civilly and criminally.

Hirsch tells Hulk in the letter ... he admires what Hulk has accomplished and then says he saw a "teaser" of the tape and believes there would be a "huge demand."

Huge or not ... Hulk and his lawyer could not have been clearer on TMZ Live yesterday ... they don't want that tape to see the light of day.

Hulk Hogan says the sex tape being shopped to porn companies was "secretly filmed" WITHOUT his permission ... and claims the footage is nothing less than an "outrageous invasion of privacy."

TMZ broke the story ... the grainy video which has already been shopped to Vivid Entertainment features Hulk and a mystery brunette. It's unclear when the tape was shot.

Now, Hulk's lawyer David Houston has released a statement ... saying, "Terry Bollea is appalled at the unauthorized release of a secretly filmed video."

He adds, "[Hulk] neither approved of the filming nor the release of the same.  It is clearly an outrageous invasion of privacy and breach of trust if it is genuine.  We will take all necessary steps to enforce both civil and criminal liability.”

A sex tape featuring legendary wrestler Hulk Hogan has surfaced -- and TMZ has learned, it's currently being shopped to a major porn studio.

We've seen a portion of the grainy footage -- featuring Hulk getting undressed and a naked, unidentified brunette lying on a bed. The woman is NOT his ex-wife Linda or his current wife Jennifer McDaniel.

In the clip, Hulk pulls his shirt off and brags to his companion, "I started to work out again." Hulk then runs his hands through his blonde hair like he always does.

The best part ... Hulk's thong-shaped tan line.

It's unclear when the tape was shot -- but Vivid honcho Steve Hirsch tells TMZ, he was approached with the tape very recently by a third party.

So far, no word on whether Hirsch or anyone else has made an offer to buy the tape.

Hulk did not have an immediate comment. 


Hulk says the tape was "secretly filmed" without his permission -- and now his lawyer's on the rampage ... claiming, "We will take all necessary steps to enforce both civil and criminal liability.”

A British woman who's become a celebrity in the U.K. because she was born with two fully formed vaginas may finally be able to cash in on her crotch ... TMZ has learned she's just been offered $1 MILLION to bone on camera.

Her name is Hazel Jones -- and the 27-year-old beauty has been making the media rounds across the pond to discuss "uterus didelphys" ... a condition which caused her to develop 2 sets of female reproductive organs. In other words, two vaginal canals with two openings. 


Hazel recently told British tabloid The Sun that she's not shy about her condition -- insisting she and her husband have shown it off at sex clubs around the U.K.

Enter Vivid Entertainment honcho Steve Hirsch ... who heard Hazel's story ... and immediately reached out to the woman with a MASSIVE offer to film her double hoo-ha in action.

In the letter, Hirsch writes, "You are obviously an extraordinary woman and I would like to make you an offer to star in an upcoming Vivid production. We would pay you up to $1 million for your services."

For the mathematically challenged, that's $500k per vagina.

To sweeten the deal, Hirsch says Jones can pick any XXX partner she wants in her movie -- adding, "We would fly you out to L.A. as soon as you are available and provide you with first class accommodations."

We're told Hirsch has not heard back yet.

Dating a porn king has brought Melissa Rivers into the adult film universe -- and now one company wants her to take it a step further, and make an adult tape of her own!

As TMZ first reported, Rivers is now dating Steven Hirsch the head man at Vivid Entertainment ... a company famous for selling celebrity sex tapes.

But another adult company, PornHub.com, has fired off a letter to Rivers to see if she and her new BF would be interested in filming a tape for them. The company believes it would be the first sex tape to feature "a sexy Jewish American Princess."

Some barriers are never meant to be broken.

Joan Rivers' only daughter Melissa has been meeting with the king of celebrity sex tapes Steven Hirsch ... but it ain't to star in a XXX flick, TMZ has learned the two are actually dating.

Sources close to the couple tell us Melissa -- who runs "Fashion Police" on E! -- has been dating the Vivid Entertainment honcho for a couple of weeks ... after meeting through mutual friends. 

One person with direct knowledge of the situation tells us, "The relationship is going great."

Hirsch has brokered nearly every major celebrity sex tape on the market ... including Kim Kardashian, Shauna Sand and Chyna ... but he's never starred in one ... so don't get your hopes up.

Here's a switch.  Porn giant Vivid Entertainment claims it's been violated ... by a phone.  Ouch.

Vivid has fired off a cease and desist letter to HTC America, claiming the mobile phone maker's newest model -- Vivid -- infringes on its trademark.

Lawyers for Vivid ... the company that gave us the Kim Kardashian sex tape ... claim consumers might get confused and think Vivid is behind the phone ... not in a sexual way, of course.

The letter threatens that if HTC doesn't change the name of the phone by Monday, they're headed to court.

Come to think of it ... a Vivid Entertainment phone would be awesome.  Think of the screensaver.

We've reached out to HTC's reps ... so far, no comment.

Vivid Entertainment president Steven Hirsch thinks Sasha Grey is the porn version of Jackie Robinson ... hoping she's opened the door for other adult stars to read books to kids.

As TMZ first reported, Sasha read children's books at Emerson Elementary School in Compton on November 2 as part of the Read Across America program. Even though we have photos of Sasha reading to kids, a rep for the school denies she was ever there. 

Regardless, Hirsch fired off a letter commending the school for allowing Grey to appear. In the letter, Hirsch offers up two of his stars -- Chyna and Allie Haze -- as possible future volunteers.

So he's saying there are three porn stars who can read? Who knew?
