Sex

TMZ has learned Montana Fishburne is starring in a porno flick for Vivid Entertainment -- explaining, "I've watched how successful Kim Kardashian became and I think a lot of it was due to the release of her sex tape."

Unlike the celeb she admires -- Montana, who also goes by the name "Chippy D," is not arguing that her tape was stolen or obtained illegally.

We're told the flick is set to be released in August.

Montana also talked to CarltonJordan.com about her new gig, saying "The first time is really nerve racking ... but, I have a lot of at-home experience."

The guys behind the movie -- a semi-biopic about the first Internet porn moguls -- tell TMZ the orgy scene would have pushed the R-rated film into "NC-17" territory ... so they simply dropped it.

Lindsay is the target of a new porn parody featuring a crying, bitchy, whorish LiLo look-alike -- who just like the real Lindsay ... takes some serious punishment from the long arm of the law.

The flick -- titled "Hustler’s Untrue Hollywood Stories: Lindsay Goes to Jail" -- even features a spoof of Lindsay's lawyer, the effervescent Shawn Chapman Holley.

As TMZ first reported, Vivid Entertainment president Steve Hirsch offered Chapman a potentially lucrative deal to star in one of Vivid's adult films -- but according to a rep for Vivid, Anna just ain't down with getting down on film.

According to the rep, Chapman's lawyer claims the Russian spy has "no interest in our offer or in adult films."

Shepherd testified after having a preemie baby weighing 1 pound, 10 ounces, she was going back and forth to the neonatal intensive care unit for several months. She said one day upon returning home, she found pictures of her husband Jeff Tarpley having sex with a random woman, whom he later impregnated.

Shepherd filed for divorce shortly after finding the photos, back in 2006.

Levi and Bristol's story is a tale of classic romance ... he knocks her up when she's 17, she has a kid (Tripp), they break up, they attack each other in the media, he poses for Playgirl, they attack each other in the media again ... and then they reconnect during custody negotiations about three months ago.

But the best part: The couple claims they didn't tell Bristol's mom -- Sarah Palin -- about the engagement first. Instead, they told Us Weekly ... and hoped that it was one of the "variety of sources" she reads.

Levi and Bristol claim they hope to get married in the next six weeks -- and due to Bristol's abstinence pledge, they won't be having sex again until after they say "I do."

As for the wedding -- they want to get married in Alaska ... and Bristol wants Levi to wear a camouflage vest.

The banners -- which had such delightful phrases as "TIGER DID YOU MEAN BOOTYISM" and "SEX ADDICT? YA, RIGHT. SURE. ME TOO!" -- were commissioned by an anonymous person back in April.

Ted from NationalSkyAds.com says he has been hired to fly two banners over Pebble Beach today. The first will say, "TIGER: ARE YOU MY DADDY?" and the second will read, "HAPPY FATHER'S DAY TIGER LOL."

Tiger Woods' former swing coach says Woods underwent treatment for sex addiction during his five-month absence from golf, this according to an interview with The Golf Channel.

Hank Haney, who split from Woods earlier this week, also said he saw no signs that Woods ever took performance-enhancing drugs -- an allegation that has hounded Tiger over the years.

Haney said, "The only thing that I knew about was his issue with the sex addiction."

According to the legal doc -- a copy of which was filed in court because a contestant was a minor -- the contestants promise the following: "Neither I nor any members of my family or my friends will enter into any personal, social, business, and or financial relationships with any of the judges, host(s), guest stars ..." The prohibition runs for the duration of the show and 6 months thereafter.

But the way we see it ... there's no way the contract can bind family or friends. Nonetheless, it's a good threat, because according to the doc, a contestant will be disqualified for violating the rule and forfeit any prize money.

And in the money department ... here's the way it breaks down.

TMZ has learned production just wrapped on the gay porn parody "Jersey Score"-- with Dean Coxx playing the lead role of "The Stimulation."

Back in 2009, Kayden Nguyen appeared in an episode titled "The Gay Kingdom" -- in which she bragged, "I can use my sex appeal to get any girl that I want and trick any guy to getting what I want."

As TMZ first reported, Kayden filed a lawsuit against Seagal claiming she took a job as his executive assistant ... but was instead treated like a sex servant.

According to a couple of Jeff Beacher's infamous Oompas, the allegedly straying golfer also likes 'em short, orange and topped with green hair.

We're told Rob Kardashian has been dating none other than Lisa Ann -- the adult film star who headlined the XXX classic, "Who's Nailin' Paylin?" Rob picked up Lisa Ann at the gym right around the time of Khloe's wedding.

Lisa Ann tells us, "Rob treats me like his little teacher and we have a fun sexual relationship that is simple and carefree. He brings out the total cougar in me and I just like to teach him things."

By purchasing messy, lubricated inside and out Lifestyles X2 condoms, the 39-year-old is still on a slippery slope.

Bristol Palin may wanna cover her ears -- Brooke Shields claims she would've swiped her V-card a lot sooner if she wouldn't have had so many issues with body image.

In a ridiculously candid interview with Health Magazine, Brooke said her biggest health regret was "Not learning to love the way I looked earlier. And I think I would have had sex a lot earlier! I think I would have lost my virginity earlier than I did at 22."

If you happen to be an exhibitionist, the Happiest Place on Earth just got a little happier -- 'cause Disney is dropping their last line of defense against roller-coaster boobie flashers.

It's all over rides like Splash Mountain -- aka Flash Mountain -- where some people would whip out certain body parts in the hopes that the park camera would catch the nudity ... and then display the naked shot on the photo preview screens for all to see.

Disney had created "image screening positions" to prevent the XXX shots from going public. But now, execs have told the OC Register the screeners have been "redeployed" -- and that they no longer need to monitor the rides because "actual inappropriate behaviors by guests are rare."

But before you run out and bare all, Disney claims they're still going to patrol the park for flashers ... and anyone who tries to turn the place into their own adult Fantasyland will still get a taste of Mickey's size 24.
