——On 19 October 2007, Rowling was asked by a young fan whether Dumbledore finds "true love." Rowling said that she always thought of Dumbledore as being homosexual and that he had fallen in love with Gellert Grindelwald, which was Dumbledore's "great tragedy"; Rowling did not explicitly state whether Grindelwald returned his affections.
——Rowling explains this further by elaborating on the motivations behind Dumbledore's flirtation with the idea of wizard domination of Muggles: "He lost his moral compass completely when he fell in love and I think subsequently became very mistrustful of his own judgement in those matters so became quite asexual. He led a celibate and a bookish life."
——2007年10月19日，一个年轻的粉丝问罗琳邓布利多是否找到了“真爱”。罗琳说，她一直认为邓布利多是同性恋，他爱上了盖勒特·格林德沃，这就是邓布利多的“伟大的悲剧”；罗琳没有明确说明格林德沃是否回应了他的感情。
——罗琳通过详细阐述邓布利多对于巫师统治麻瓜的思想不成熟的考虑背后的动机，进一步解释了这一点：“当他爱上格林德沃时，他完全失去了自己的的道德方向，我想他后来变得非常不信任自己对这些事情的判断，所以一直很禁欲。他引领了一个单身主义的，书呆子般的人生。”
