Exclusive: Leading Nude Site Turns Down $100,000 Offer for Leighton Meester Sex Tape, But Which Naked Celebrity Is the Most in Demand?

Paris Hilton, Pamela Anderson, Kim Kardashian and Elizabeth Jagger have all catapulted to new heights of fame thanks to the leakage of unauthorized sex tapes — so is it just a matter of time before Leighton Meester joins the line-up?

An alleged sex tape of the "Gossip Girl" (believed to be shot with an ex-boyfriend when she was 18 years old) made the Tinseltown rounds last week with a price tag of a cool $100,000.

"It was definitely a legitimate offer and it was from a professional who has done this before," confirmed Jim McBride, owner of MrSkin.com, the world’s leading source for celebs flashing the flesh who was approached by the seller on Thursday.

"But we passed, it’s not our thing. I celebrate nudity in movies and TV, but always with respect for the actresses who choose to bare their bodies on-screen. Homemade sex tapes fall beyond that scope. When Leighton Meester is ready to do a proper movie or TV nude scene — on her own terms — Mr. Skin will review it, report on it, and celebrate Leighton in the fashion that has made our site famous. Until then, out of respect for her talent and beauty we want nothing to do with the tape."

So with Meester momentarily out of the running, which flesh-flashing famous figures are currently the most downloaded?

"Jessica Biel is extremely popular. Not a lot of people actually saw "Powder Blue" but her nude scene is outstanding - as good as I can hope," added McBride. "And another one who is extremely hot right now is Anna Paquin. Her sex scene on "True Blood" was also outstanding."

Julianne Hough Terrible In Footloose Audition?

Reports have been running rampant that dancer-turned-country crooner Julianne Hough has been offered a role in the upcoming "Footloose" remake, but according to our insider source the blonde beauty still has a lot of work to do before she seals the deal.

"Her acting was so bad that the producers sent her off to take some classes and practice and she's not scheduled to go back for her next screen test until August first," said our inside snitch. "And they’re still auditioning a ton of girls …"

We're told that if Hough can "deliver a good line" by this date, the part (starring alongside Chace Crawford who recently stepped in when Zac Efron pulled out) will be hers.

Heidi Klum Gets Own Barbie Doll

Heidi Klum is a supermodel, an Angel, a TV host, an entrepreneur, a mom, a wife and now she’s a made of plastic too. Literally.

Pop Tarts confirmed that Klum is getting her very own Barbie Doll, which hits the shelves in September and will be part of Barbie’s Blonde Ambition Collection, a series celebrating iconic blondes in fashion and entertainment. But let’s not forget Pop Tarts first suspected the German-born beauty was soon going to be made of Mattel plastic at Barbie’s 50th Birthday party in Malibu back in March.

"You guys just have to hold onto your horses a little while longer and then maybe then you’ll know and see," the Project Runway starlet said with a smile after we asked what she would envision her own Barbie to be like — hypothetically speaking.
