The actress, who plays Luna Lovegood in the big screen adaptations of the book series, revealed that her psychic has informed her that Potter author JK Rowling is hard at work on more books.
"I went to a psychic today," Lynch told E! Online. "And the first thing she said was, 'She'll write more books'."
Lynch went on to say that whenever she sees Rowling, the writer is hard at work.
Every time I see her she's like, 'Yeah, I'm writing'. I hope that she's writing more [books]!"
In August, Lynch announced that she is planning to move to Hollywood in a bid to further her acting career.
Earlier this year, the actress confessed that she cried on the last day of filming Harry Potter and the Deathly Hallows: Part Two, saying that she was not ready to walk away from the series.
