Washington, Apr 4 : Hollywood beauty Scarlett Johansson who has insisted on a no nudity clause in her movies, may have to rethink if she wants to play porn star Jenna Jameson.

The curvaceous 22-year-old is determined to be seen as a serious actress and now won't commit to any role without the 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 was quoted by Tittle Tattle as saying.

"She doesn't want to fall into being too controversial or too trashy so nude scenes are out for now," he added.

However, the 'Lost In Translation' star has reportedly been singled out by X-rated actress 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 Johansson. She's my choice. I think she's beautiful," Jameson said.
