Leave it to Barbara Walters to ask Oprah Winfrey about the rumor that just won’t seem to go away: Is Winfrey’s best friend Gayle King really her lover?

Tonight ABC will air a Barbara Walters special titled Oprah: The Next Chapter” that looks at Oprah’s 25-year television career and yes, her personal life. Including, as Oprah would yell: lesbian ruuuummmooors!

Winfrey has consistently denied these rumors, but in tonight’s show

Walters asks her one more time. “I’m not even kind of a lesbian,” Winfrey answered.

“And the reason why [the rumor] irritates me is because it means that

somebody must think I’m lying. That’s No. 1. No. 2, why would you want

to hide it? That is not the way I run my life,” Winfrey told Walters.

Winfrey’s sexuality rumors have followed her for years.

“Investigative journalist” Kitty Kelley released an unauthorized

biography in April, alleging Winfrey has gone through great lengths to

conceal her “lesbian affairs”–including hefty payoffs–and publicly

attached herself to her long time boyfriend Stedman Graham so she can appear

more normal to her audience of housewives.

But the real news here is Barbara

Walters hasn’t learned a thing about asking celebrities about their

sexuality.

Oprah’s best friend Gayle King denies rumors also.

“In 2000, I pushed Ricky Martin very hard to admit if he was gay or not, and the way he refused to do it made everyone decide that he was,” Walters told the Toronto Star. “A lot of people say that destroyed his career, and when I think back on it now I feel it was an inappropriate question.”

Yeah, girl. So mind your own business.

The interview airs Thursday on ABC
