*Author Kitty Kelley is still plugging her biography on Oprah Winfrey with the recent revelation that employees for the talk show host don’t use her real name when discussing her in public.

According to Kelley, staffers use the code name “Mary” instead.

“That way, when they’re talking about her, and someone overhears the conversation, no one knows they’re referring to Oprah,” Kelley told the New York Post’s Page Six.

Oprah dismissed Kelley’s book last month, calling it a “so-called biography” and mocking Kelley’s claim that she knew who Oprah’s father was.
