Natalie Portman is set to play a prostitute in her new movie.

The 'V for Vendetta' star is reportedly auditioning for the role of a troubled hooker in dark comedy 'Johnny Postal'.

If she gets the part, Portman will star alongside Blondie singer Deborah Harry who is to play a "sex-crazed, biker b***h past her prime".

Another music star confirmed for the film is world famous DJ Roger Sanchez who plays a "drug-dealing pimp".

Shooting on the movie starts this coming autumn and will take place in New York and New Jersey.

Meanwhile, Portman appears nude in her latest film.

The actress will be seen completely naked during torture scenes in the upcoming historical drama 'Goya's Ghosts', which focuses on revered artist Francisco Goya.

Portman plays Goya's muse, Alicia, and becomes embroiled in a religious scandal after she is accused of being a heretic by a monk.

It is not the first time Portman has stripped off for a movie role.

She previously exposed her body in the complex romantic drama 'Closer', which also starred Jude Law, Julia Roberts and Clive Owen, but the explicit scenes were eventually cut. (source:Life Style Extra)
