Hollywood [Fox News}- Sexy screen siren Scarlett Johansson is making sure her private parts never become public parts.

The 22-year-old “Scoop” sensation is reportedly refusing to commit to any contracts that don’t have a no-nudity clause.

“Scarlett is still very young and is aware the roles she takes are going to set out where her career as an actress takes her in the future,” a source told Britain’s Daily Express newspaper.

“She doesn’t want to fall into being too controversial or too trashy, so nude scenes are out for now.”

But for all the moping males out there, the chance of seeing the voluptuous vixen flash the flesh is not completely lost.

Johansson has apparently been singled out by porn princess Jenna Jameson to play her in a film movie adaptation of her autobiography “How to Make Love Like a Porn Star: A Cautionary Tale.”

“We’re looking at Scarlett. She’s my choice. I think she’s beautiful,” the adult actress told the Daily Record.

Sources close to Johansson have said that she’s very keen on the role, believing it could create a path to an Academy Award.

While Scarlett may be the male ideal of a red-hot fantasy, she has been snubbed as the sexiest star on screen by one-time love rival Jessica Biel.

Both Johansson and Biel were rumored to have been bringing the “SexyBack” into Justin Timberlake’s life earlier in the year.

However, Biel has beaten the “Black Dahlia” to take the top spot in the 100 Sexiest Women poll by men’s magazine Stuff.

Scarlett scored a silver, while brunette beauties Jessica Alba, Eva Longoria and Katharine McPhee scooted in behind.
