In an interview with the NY Times, biographer Kitty Kelley (pictured) alleged that some of television’s biggest shows would not book Kelley to promote her upcoming unauthorized biography of Oprah Winfrey.

Here’s an excerpt: “In promoting this book, we have already been told by Barbara Walters‘s producer, No, you cannot be on The View, I cannot disrupt my relationship with Oprah. Joy Behar, the same thing. Charlie Rose; Larry King said, I will not do it, it might upset Oprah. Even David Letterman.”

UPDATE: A CNN insider told us this afternoon: “Larry King hasn’t spoken with Kitty Kelley in five years.”

Kelley’s 544-page biography of Winfrey’s life debuts on April 13. Kelley has written juicy books about the Bush family, Nancy Reagan, and Frank Sinatra and many other public figures. In mid-April, mediabistro.com will feature an exclusive Media Beat interview with the biographer about this book. In addition, here’s an old Larry King interview with the author.
