Barbra Streisand^[1] remembers the way we were — but she’s having trouble finishing her autobiography.

Viking Books announced in 2015 that it would be published last year, but the diva hasn’t even turned in a rough draft, and the book won’t come out this year, either.

“She’s been working on it for 2 ¹/₂ years,” one insider told me. “She’s such a perfectionist. She’s probably going over it word by word.”

Streisand might also be struggling with how many misty watercolor memories to reveal about her rumored affairs with Warren Beatty, Ryan O’Neal, Kris Kristofferson, Don Johnson, Jon Voight, Richard Gere and Liam Neeson.

“My guess is it will be a little sanitized,” my insider said.

“It will come out when it comes out,” a Viking source said. “The support for her autobiography is undiminished. It’s worth waiting for.”
