Billie Eilish makes her acting debut in ‘Swarm.’ The GRAMMY winner's scenes were released as part of a sneak peek of the Prime Video series. Dominique Fishback toplines the show, playing an 'obsessed fan of the world’s biggest pop star.' In addition to Billie's casting, the show's fictional pop star, as well as its title, parallels Beyoncé's fandom, the ‘BeyHive.' The series, co-created by Donald Glover, premieres March 17.
