JK Rowling has dropped a massive bombshell by revealing that she's got a secret manuscript stashed away – and only the moths in her wardrobe can read it.
Harry Potter fans will be dismayed to hear the writer has no direct plans to publish the story, because it's written on one of her dresses.
During a recent interview with CNN, the 51-year-old author revealed that the manuscript of almost an entire book was written on to the frock last year for her 50th birthday party.
Joanne asked pals to come dressed as their "worst personal nightmare", and her own was a lost manuscript.
She set about scribbling away on a gown, which then became a garment and an original JK Rowling story combined.
How much that dress is likely to be worth now doesn't bear thinking about.
The writer said: "I wrote over a dress most of that book.
"So that book, I don't know whether it will ever be published, but it's actually hanging in a wardrobe currently."
