NYC Mayor’s wife....
And the actress Anne Heche. She claimed to be lesbian when she was going with Ellen de Generes. Eventually she married a man.
So these are at least two examples of famous people who at one time claimed to be homosexual, then changed their minds.
RE: NYC Mayor’s wife....
Actress Ann Heche, former girlfriend of Ellen Degeneres.
Heche has stated that all of her ensuing romantic relationships have been with men.
