Fans have always been a major part of celebrity culture. Most of us have been huge fans of someone at some point in our lives. Maybe it was a singer whose posters covered our bedroom walls, an actor whose movies we watched over and over again, or a celebrity we followed online every single day. There is something exciting about admiring talented people and wanting to know more about them beyond their music, movies, or public image. That connection can feel personal, even when the celebrity has never actually met us.
