Diane Keaton

Being one of the legendary actors of Hollywood, Diane Keaton remained unmarried all these years. In fact, in 2019, she made remarks on how she has never dated in 35 years. She’s in her 70s now, which could be a bit of a feat, especially after long years of hiding away from the market.

Although, all through her career and movie credits, she has been involved with big men in the industry. Not one, really, made it to marriage. In fact, the only time she referred to someone as the love of her life was in 2008, talking about her mom when she lost her.
