J.K. Rowling has a little wizard on the way. The Harry Potter creator announced Thursday that she is preggers with her second child — her first with hubby No. 2, Dr. Neil Murray. The news comes on the heels of a federal court's decision Wednesday to throw out a plagiarism suit in which author Nancy Stouffer accused Rowling of stealing characters and words — including the term "muggle" — from Stouffer's series of Larry Potter books. Meanwhile, Rowlings assures fans that her much-anticipated fifth Potter book is on its way.
