Chances are, if you're famous enough to have an authorised biography, you're famous enough to have some bad publicity as a result of it.
As Simon Cowell has recently discovered following last week's publication of Tom Bower's Sweet Revenge: The Intimate Life Of Simon Cowell, secrets you didn't even know you kept can raise their ugly heads when somebody else writes your life story.

Whether you believe their tall tales or not, chances are you'll want to check at least one out from your local library.
