J.K. ROWLING has leaked the ending of the last ever Harry Potter book to her husband, according to actor Daniel Radcliffe. The author will be releasing the seventh and final installment of the boy wizard series, Harry Potter and the Deathly Hallows next month (21Jul07) - and she is keeping the ending so under wraps not even the actor who plays the teen wizard knows the outcome. Radcliffe says, "None of us get a preview. I think only J.K. Rowling's husband has recently found out what happens. I don't think anyone else knows."
