The new "X-Men 3" movie is to have a new character - "an unbelievably hot and sexy hooker".

"Her super power is that she secretes a pheromone that helps her to seduce men. She can seduce anyone," The New York Post reports, quoting a source.

New director Brett Ratner ("After the Sunset"), who took over after Matthew Vaughn stepped aside for personal reasons, had the dream character written into the movie.

The source added that the character has not been cast yet.

"They are open to all ethnicities who are in their early-to-mid 20s. Two unknowns who seem to be in the lead to snag this role are Kate Nauta and Aya Sumika," the source said.

The lucky actress to be selected for the role will join the stellar cast comprising Hugh Jackman, Oscar winners Anna Paquin and Halle Berry - and Patrick Stewart.
