One fan asked whether Albus Dumbledore, the head of the famed Hogwarts School of Wizardry and Witchcraft, had ever loved anyone. Rowling smiled. "Dumbledore is gay, actually," replied Rowling as the audience erupted in surprise. She added that, in her mind, Dumbledore had an unrequited love affair with Gellert Grindelwald, Voldemort's predecessor who appears in the seventh book. After several minutes of prolonged shouting and clapping from astonished fans, Rowling added. "I would have told you earlier if I knew it would make you so happy."
