HOLLYWOOD sirens Scarlett Johansson and Jessica Simpson have rejected reports they will take on the role of Jenna Jameson in a biopic about the porn queen.

Jameson's book "How To Make Love Like a Porn Star" - is to be re-titled Heartbreaker for the film.

Johansson was first pick for Jameson, who revealed earlier this month that she was a big fan of the actress' performance in Lost in Translation.

"I remember thinking to myself, this girl has such a sexuality without even really trying to be sexy. I was like, 'This girl could play me.'

"I love her. She's amazing. She's smart, she's funny. ... She's stunning.

"I don't want someone who's going to go in there and be like bouncing around. I want someone who can bring some depth."

But it seems Johansson doesn't share the same enthusiasm, with her representative telling People.com, "Scarlett has never seen a script nor been approached about this project. She also has no interest in playing this role."

Simpson also turned down the role because she refuses to do nudity in movies. Even the lure of a possible Oscar didn't make her budge. Her dad Joe Simpson said: "The last script that came to us was for Jessica to be a porn star. We were promised we would win an Oscar with that.

"I was like, 'We'll just buy a little man and keep our clothes on."
