According to Entertainment Weekly:
Responding to a question from a child about Dumbledore’s love life, Rowling hesitated and then revealed, “I always saw Dumbledore as gay.” Filling in a few more details, she said, “Dumbledore fell in love with Grindelwald…. Don’t forget, falling in love can blind us. [He] was very drawn to this brilliant person. This was Dumbledore’s tragedy.” She added that in a recent meeting about the sixth movie, she spied a line in the script where Dumbledore waxed poetic about a girl, so she was forced to scribble director David Yates a note to correct the situation.
