Which character did Mariah Carey play in the film "Glitter"?

Mariah Carey played Billie Frank in the film Glitter.

Released in 2001, Glitter is a musical drama directed by Vondie Curtis-Hall. Carey plays Billie, an aspiring singer who begins as a club dancer alongside her friends Louise and Roxanne. The story follows Billie's rise from performing backup vocals to pursuing a solo career, while also exploring her troubled relationship with her mother and her romance with nightclub DJ Julian “Dice” Black.

The role was closely connected to Carey's own work on the project. She helped develop the film's concept and recorded its accompanying soundtrack, which includes songs such as “Loverboy,” “Never Too Far,” and “Reflections (Care Enough).” The project had originally been developed under the working title All That Glitters before the film was renamed Glitter.

Viewers sometimes confuse Billie Frank with Lillian Frank, Billie's mother in the story, or with Billie’s friends Louise and Roxanne. Louise was played by rapper Da Brat, while Roxanne was played by Tia Texada. Carey portrayed the central character, Billie, not any of those supporting roles.
