Oprah Winfrey Barbara Walters Interview: "I'm Not a Lesbian" Video

TV's queen of talk Oprah Winfrey sat down for a rare interview with Barbara Walters for an upcoming special where she talked about her friendship with Gayle King and her relationship with Stedman Graham.

Oprah broke down into tears as she denied she is a lesbian during the emotional interview.

"She is ... the mother I never had," Winfrey said about King, 55. "She is...the sister everybody would want. She is the friend that everybody deserves. I don't know a better person. I don't know a better person."

Winfrey, 56, continued "It's making me cry because I'm thinking about ... how much ... I probably have never told her that," she said.

"I'm not a lesbian...I'm not even kind of a lesbian," Winfrey said. "And the reason why it irritates me is because it means that somebody must think I'm lying. That's number one. Number two...why would I want to hide it? That is not the way I run my life."

Winfrey moved the conversation to Graham, 59, whom she has been in a relationship with since 1986. "The love, the lover, the man, the partner, the mate," Winfrey said. "I do not know of another man on this planet...who could have lived this life with such dignity, with such grace and such respect and humility in it and still hold his own and be his own."

A Barbara Walters Special: Oprah, The Next Chapter, airs Thursday, Dec. 9 at 9 p.m. on ABC. Watch a video clip from the interview below:
