Oprah's ex-stepmother, Barbara Winfrey, claims that Oprah has forced her out of the home she shared with Oprah's dad, Vernon. She's retaliating by dishing all kinds of dirt in a two-part Daily Mail interview, of which part two is entirely devoted to weirdness of the Oprah-Stedman Graham-Gayle King triumvirate.

Among other things, Barbara alleges that Oprah paid her security team to follow longtime boyfriend Stedman and learn everything about his life. At first, Stedman objected, in an argument 8 years ago, but Barbara says he's now so financially dependent on Oprah that he's "at her beck and call."

Barbara claims Oprah even bought a warehouse full of Stedman's books and guaranteed they'd make the bestseller list.

"Once you're in Oprah's world, she owns you," she says.

As for best friend Gayle, Barbara says her relationship with Oprah is "unhealthy."

Oprah allegedly took the family on an expensive 11-day mediterranean cruise and didn't speak to them the entire time. She only talked to Gayle and Stedman.

"Anytime you looked up they were together. To me it was just bizarre."

According to Barbara, Gayle was frequently the go-between for Oprah's messages to her father and stepmom, including instructions about how to handle the press. Oprah also tended to speak of herself and Gayle as "we."

"Sometimes I believe that Oprah is more dependent on Gayle than the other way around. I don't know what she would do without her friendship and if it's not more than friendship then they're certainly giving every appearance that it is," Barbara said.

Among the other, non-bizarre-triangle-related revelations in the interview: Oprah apparently has an obsession with skin color, referring to her dad and Barbara as "negroes" and envying Stedman for his "high yellow" skin tone.

She also allegedly stress-eats any kind of potato she can find. Bombshell.
