(via The Sun):

Scarlett Johansson has landed her most explicit role yet - that of the world’s biggest porn star.

The 22-year-old will take the lead role in the forthcoming, x-rated biopic of Jenna Jameson.

And legendary adult entertainer Jameson chose Scarlett specifically for the role. She explained, “I tapped up Scarlett for the part and I’m very excited about the film. It was my decision not to play the role because I’ve lived that tale already and anyone can play themselves.”

The film will be based on Jenna’s autobiography, How To Make Love Like A Porn Star.

EDIT People says she isn’t. It’s a strange split and doesn’t all quite add up to the last time this started. So your guess is as good as mine.
