JK Rowling has congratulated a fan for overcoming intense bullying by writing a heartwarming note.

Johnnie Blue met the Harry Potter creator at an event for her new book The Silkworm, and subsequently sent her a letter thanking her for helping him through difficult years.

"What you say about Harry helping you at what was clearly a dreadful time in your life means more to me than I can easily express. I freely confess that I loathe bullying and the way it is so often 'handled' in schools," Rowling replied in a letter than was shared with BuzzFeed.

"Your experience is shocking and disturbing and that you have turned out to be a compassionate, moral, highly motivated person is a high testimony to your courage. Gryffindor for you, my lad..."

This isn't the first time Rowling has spoken out against bullies. Last year she said she was "unnerved" by how many girls fancied fictional bully Draco Malfoy from the Harry Potter franchise.

“Draco remains a person of dubious morality in the seven published books, and I have often had cause to remark on how unnerved I have been by the number of girls who fell for this particular fictional character,” she wrote.
