Author E.L James can expect her fan base to widen to a much younger demographic. Justin Bieber started a rumor that he will appear in the film adaptation of James' best-selling erotic novel "Fifty Shades of Grey" during his guest appearance on the British late night talk show "The Jonathan Ross Show." The pop singer sparked the rumor on Saturday, Sept. 15. "They actually want me to be in the movie," said Bieber with a straight face referring to James' upcoming film.
