Harry Potter author JK Rowling has said she is expecting her third child, due next year.
Rowling already has a daughter and a son
The author, 38, broke the news on her website. She already has a daughter Jessica and son David, who was born last year.
Rowling said: "I always wanted three children, so I could not be happier."
The author said pregnancy would not affect the release of the new Potter book. "Let me reassure you that book six remains well on track," she said.
"Fingers crossed of course, I don't foresee any baby-related interruptions or delays.
"I still can't say for sure when it will be finished, but I have written a lot and I really like it (a reckless challenge to fate, that; I bet the next chapter goes horribly wrong now)," the author added.
The author recently revealed the title of the sixth book in the Harry Potter series would be Harry Potter and the Half Blood Prince.
Rowling has sold more than 260 million copies of the children's book series so far, with the boy wizard's adventures being made into a franchise of popular films.
The film of the third book, Harry Potter and the Prisoner of Azkaban, was released last month.
