No Diane Keaton is not a lesbian. Keaton has had romantic associations with several entertainment industry personalities, starting with director Woody Allen during her role in the 1969 Broadway production of Play It Again, Sam. Their relationship turned romantic following dinner after a late-night rehearsal. It was her sense of humor that attracted Allen.
They briefly lived together during the production, but by the time of the film release of the same name in 1972, their living arrangement became informal. Keaton said she produced her 1987 documentary Heaven because “I was always pretty religious as a kid, I was primarily interested in religion because I wanted to go to heaven.” When she grew up, she became agnostic. As of 2023, Keaton has been a vegetarian for 27 years.
