KEY POINTS:
Kitty Kelley has selected Oprah Winfrey as the subject of her next tell-all, unauthorised biography.
"Oprah has fascinated me for many years - as a woman, she has wielded an unprecedented amount of influence over the American culture and psyche," Kelley said.
Kelley, whose many bestsellers include biographies of Frank Sinatra, Nancy Reagan and the Bush family, has a long history of writing books as loathed by their subjects, and disputed by critics, as they are fascinating to readers.
