This work aims to study the culture of fans in Rio de Janeiro, its forms of communication and interaction with the city. This study also focuses on understanding how fans perceive their idols, once they present themselves to society and the media, often as superior or indefectible beings. The act of being a fan is already investigated by researchers and on the other hand carries some meanings that sometimes are pejoratives while handled by the common sense and also by some mediatic contexts. By using the subculture studies approach in an etnography it was possible to verify that the impact of the studied pop divas, Lady Gaga and Beyoncé, on their respective fandoms, Little Monsters and Beyhive, takes place not only in the entertainment area, but also in a very subjective way. The fan cultures acts as the creator of highly organized social groups both in the digital and in the real world, promoting not only their well-being, but also political and ideological debates, in order to stimulate reflection on the minorities to which they belong to, and the fight against the most diverse types of discrimination suffered by participants of the fandoms.
