This is not really a surprise. According to reports, Kevin Federline is planning to write a revealing book about his life with his superstar wife, that will claim that Britney is bisexual, and talk about her alleged drink and drug problems. A source told Star magazine: "Kevin is either hoping a publisher will pay him big money for the book or that Britney will cough up more cash than what's in their prenup to keep him from spilling the beans."
She really ought to have married someone as famous as she is.
