In an unexpected turn of events, Harry Potter authorJ.K. Rowling has only gone and revealed she's a Directioner.

In a fan shared pic of an image from Rowling's new book, 'Career of Evil', the two characters discuss a girl called Hazel who claims she's dating someone called Niall.

"They’re a band that came third on ’The X Factor,’" Hazel explains to the somewhat clueless detective after mentioning One Direction. "She’s obsessed — she was obsessed — and Niall was her favorite."

So does this mean Harry Potter will soon be seeing Harry Styles join Gryffindor?
