Kanye West writing film featuring partner Kim Kardashian

London:Singer Kanye West is reportedly writing a movie role for fiancee Kim Kardashian. The 36-year-old `Stronger` rapper is teaming up with `American Psycho` author Bret Easton Ellis to write a film on his latest album `Yeezus` and sources say the reality TV star will "definitely" be a part of it. "Kanye will not appear in the movie. Kim is definitely going to be in it. The screenplay already features her character," an insider said. The singer who has an eight-month-old daughter with `Keeping Up with the Kardashians` star has, however, not decided on how big Kim`s role is going to be in the film. "They`re still working on the script, so it`s unclear at this point if Kim will be a major star of the movie or making a smaller cameo but her role in the movie will be pivotal," the insider said. The singer "wants to be heavily involved in all aspects of production" and will dedicate the film to his late mother.
