An Oprah tell-all is coming in April, but Winfrey isn't the teller.
Crown Publishers announced Thursday that Kitty Kelley's 544-page, unauthorized "Oprah: A Biography" will be released April 13. The first printing will be at least 500,000 copies.
Kelley is known for gossipy, unflattering, but best-selling celebrity books. She has also written about Frank Sinatra, Nancy Reagan, and the Bush family.
Kelley says she has high regard for Winfrey, but also felt committed to writing the truth. Kelley says she devoted the past three years to examining Winfrey's life. She says she came away "full of admiration for her accomplishments and fascinated by her complexity."
Crown says Kelley conducted 850 interviews for the book.
