Harry Potter author J.K. Rowling is sending a strong message to the world: Don't mess with her boy wizard. Rowling and publishing giant Scholastic have slapped the New York Daily News with a $100 million lawsuit for prematurely publishing excerpts from her latest Potter book Order of the Phoenix. In related news, Rowling tells NBC's Katie Couric that she sobbed uncontrollably when she made the decision to kill off a major character in the hotly-anticipated fifth novel, which arrives in stores midnight Friday. "It was awful to write," she says. "It was absolutely awful." But then she checked her savings account balance online and felt a whole lot better.
