In the era of digital media, new media forms, media platforms, and media environments all affect the thinking and behavioral patterns of young people pursuing celebrities. The study examines the phenomenon of teenage star chasing in the era of digital media, and elucidates the chaotic phenomena that arise during the process of teenage star chasing, such as entertainment oriented, idol worship fast food oriented, and uncontrolled "fan circle" behavior. On this basis, the reasons for these chaotic phenomena of star chasing were analyzed, including the misleading values of young people caused by improper promotion of digital media, the commercialization of star idol manufacturing in the digital media era, the distortion of new star chasing mechanisms among young people, and the weak awareness of reasonable online star chasing among young people. In the context of the inability to avoid the involvement of digital media in youth star chasing, research suggests that big data algorithm mechanisms should be clarified and value education should be strengthened; Using digital media channels to promote positive energy idols; Enhancing digital media literacy and conducting offline celebrity chasing activities to strengthen education and guidance on adolescent celebrity chasing behavior.
