*Kitty Kelley’s unauthorized bio on Oprah Winfrey is headed to the small screen.

E! News is reporting that the celebrity author has optioned the movie rights of her infamous book with plans to turn it into a TV movie or miniseries.

The deal, said to be in the six figures, is with veteran producer Larry Thompson, who has filmed biopics on Lucille Ball and Desi Arnaz, Sonny and Cher, and the Duke and Duchess of Windsor.

Thompson says that the plan is to develop the project to coincide with Winfrey’s final syndicated episode in September 2011, with an unknown actress in the lead role. (Winfrey is slated to sign off on Sept. 9, 2011.)

So far, Oprah has yet to comment.
