For Carrie Fisher, the forthcoming Star Wars film, The Force Awakens, is not only a chance to reprise her iconic role as Leia Organa, Princess of Alderaan turned General of the Resistance, but also work with her real-life daughter. Billie Lourd, the 23-year-old female offspring of Fisher and talent agent Bryan Lourd, will make her cinematic debut in the film.
Her role remains shrouded in mystery, though she has shot down rumors that she’ll be playing a younger version of Leia.
