J. K. Rowling has been writing under a pseudonym

Apparently being the 9th most popular celebrity with an annual income of $300 million per year wasn't enough for J. K. Rowling, who was recently outed as having published a mystery novel under the pseudonym Robert Galbraith. Galbraith's novel The Cuckoo's Calling received good reviews, if only modest sales (1,500 copies sold on Amazon from the book's release in April until it was outed in early July). 

I have to give Rowling credit for her commitment to writing. If I earned that much money I personally would have a lot of trouble getting motivated to work on another book.
