Gossip / Rumors

Steve Hirsch -- Vivid Entertainment's head honcho -- tells TMZ ... if a sex tape exists he's determined to buy it ... to make sure it never sees the light of day.

Hirsch tells TMZ, "After everything that Demi Lovato has been through, we would never consider distributing a sex tape with her. In fact, we would purchase it and either give it back to her or destroy it."

So why, you ask, would the Prez of Vivid do something so counterintuitive?

Hirsch is a recovering addict and even owns Hollywood Recovery Services, an outpatient recovery center.

Back in 2008, the Disney starlet vowed to abstain from sex until marriage and donned a promise ring to prove it. But last weekend Selena was spotted going into Justin's tour bus without the chastity symbol around her pure little finger.

There's a story circulating that Paris and Doug shot the squeakquel to "One Night In Paris."

But Doug says, no way. His rep, Amanda Ruisi, tells TMZ, "Doug says a sex tape with Paris and him doesn't exist and never existed."

The downside for Doug ... we're told Rick Salomon made $10 million the first year after his epic sex tape with Paris was released.

TMZ has obtained a letter from the folks at Pornhub.com, offering Demi a chance to be featured on their site. The company is obviously excited (no pun intended) at the idea of a Demi sex tape -- even though her people say the rumors are "disgusting."

Pornhub is offering Demi $100,000 for the tape -- even offering her the caveat that, "You don't have to star with male talent, we are willing to accept a solo or Girl-Girl scene just as long as it's shot in HD."

Demi's rep tells TMZ, "Perpetrating these completely unfounded rumors from supposed sources while Demi is in treatment dealing with serious physical and emotional issues is disgusting."

The rep goes on: "The sourcing on this report is so spotty that it is hard to fully respond."

As for claims that Demi's uncle, Francisco Lovato, kept people out of her tour while she had sex inside, Lovato's rep bristles, "Francisco Lovato is the brother of Demi's estranged father. He never traveled on the tour, and certainly didn't serve as some sort of chaperone."

Julia gave this statement to TMZ: "I have absolutely nothing to do with the split between Michael and Jennifer."

Julia goes on: "We are good friends and enjoyed working together. This is a personal matter between them, and we should respect their privacy."

The two international pop stars sat down for breakfast yesterday in Philadelphia .... hours before they were scheduled to perform at the Q102 Jingle Ball.

According to the good folks at IHOP ... Biebs, 16, and Gomez, 18, HELD HANDS inside the restaurant ... and looked "cuddly" while sitting on the same side of a booth.

Erin Barry -- wife of Tony's former teammate Brent Barry -- just went to her website and wrote, "I DID NOT HAVE AN AFFAIR WITH TONY PARKER, nor did I 'pursue' Tony Parker."

She continues, "Unfortunately, because our divorces are occurring at the same time, great speculation has been cast on our friendship."

"My friendship with Tony Parker had nothing to do with the end of my marriage (which is painful enough without this added drama), and to assume that we had an affair is naïve, ridiculous, and completely misguided."

See the entire statement after the jump ...

Sources tell us the duo have been in the past several mornings and "looked like they were more than friends" ... whatever that means.

Travolta was in Australia for the 90th anniversary of Qantas airlines, and vowed to return if Kelly went into labor. According to the Herald Sun, that's exactly what happened.

A Salt Lake City radio station started the pregnancy rumor this morning, but a rep for the 18-year-old tells TMZ it's 100% not true.
