The memoir looks back at her long career and her interactions with several of Hollywood’s most famous stars.
And in one especially shocking anecdote, Streisand opens up about the time she met The Godfather star Marlon Brando.
Back when she was married to her first husband Elliott Gould, she ran into Brando - and in the book, she revealed what he said to her left her gobsmacked.
“He’d hit on a fantasy of mine … to walk through a museum with someone I was very attracted to and look at great art … exploring it together,” Streisand wrote.
But the conversation then took a turn, with Brando telling her that “I don’t think you’re going to be with Elliott much longer”.
She added that Brando said her husband wasn’t handsome enough for her, writing that she was “taken aback” by the comment.
“I’m married to him. What do you mean?” Streisand replied, with Brando responding, “He’s not good‑looking enough for you.”
Streisand did in fact go on to separate from Gould in 1969, then marrying James Brolin in 1998.
Elsewhere in the book, she wrote of losing her virginity to a man after spending time together smoking weed.
She wrote that the anonymous man acted like “nothing had ever happened” between them afterwards.
Streisand is the latest Hollywood star to release a tell-all book, following in the footsteps of Jada Pinkett-Smith and Britney Spears.
