Cher is sharing some candid memories about growing up in Hollywood.

In an excerpt adapted from her new memoir, “Cher: The Memoir, Part One,” the legendary singer, 78, writes that she met Hollywood icon Warren Beatty, 87, when she says she was 15 and spent a night swimming in the actor’s pool until 4 AM, all while wearing Natalie Wood’s swimsuit.

What’s more, the recent Rock & Roll Hall of Fame inductee says she and Beatty shared a kiss on that fateful night before going on two more dates.

Curiously, Cher stated in previous interviews — including one with Elle in 2018 — that she was 16 when she met Beatty.

However, her new memoir does gel with past comments she made about how she ran into Beatty — or rather, how he ran into her. According to the star, she and Beatty had their meet-cute after he cut her off while driving on LA’s famed Sunset Boulevard.

“Pulling into the parking lot of the famous Schwab’s Pharmacy, I jumped out and yelled, ‘What the f–k’s the matter with you? You almost hit me!’” Cher writes in the excerpt published by DailyMail.

“The man was wearing big, black-framed sunglasses, but I could still tell that he was unbelievably handsome, with one of the sexiest smiles I’d ever seen. When he took off his glasses, I realized that it was Warren Beatty.”

Beatty, then 24, had just starred in the 1961 movie “Splendor In The Grass” alongside Natalie Wood, whom Cher says Beatty dated after working with her on the film.

“Ten years older than me, Warren was so drop-dead gorgeous I had to steady myself as he asked my name,” Cher recalled.

When Beatty allegedly asked her if she wanted to “get something to eat,” the Oscar-winner “hesitated” at first.

“It was close to my curfew, and I was already worried I’d be late but then I thought of how much of a fan my mother was, so I shrugged and said, ‘Sure,'” she remembered thinking.

But Cher really swooned when Beatty supposedly invited her to his place. “My knees almost buckled in the face of his charm and that smile — a devastating combination,” she continued. But she pushed aside any reticence she felt, and told him, “Okay.”

After following Beatty in her own car up to his “beautiful house with an amazing pool in Beverly Hills,” she says things got a little romantic.

“He showed me inside, fixed us some cheese and crackers, then leaned in and kissed me.”

She added, “Now, this is interesting, I thought as I kissed him back.”

Cheese, crackers and a kiss then allegedly turned into an all night pool party.

“The two of us went swimming, with me in Natalie Wood’s bathing suit, and we had a great time,” Cher went on. “Afterward I drove home in a happy daze at 4am and found Mom and [step-father] Gilbert [LaPiere] standing on the doorstep in their nightclothes, furious that I’d defied my curfew again.”

When Beatty called her the following morning and asked her out to dinner, Cher shut him down, all too-aware of her mother eaves-dropping on the call.

After the “Shampoo” star suggested they go swimming, Cher says she laughed “at his random suggestion.”

“I didn’t want him to know how young I was or that I was grounded, so I told him, ‘My mother’s p—-d with me for getting home late, so I’m not going any place,” she added.

“Let me talk to your mom,’ he laughed. I wish I had a photograph of the look on her face when she realized who she was speaking to. She literally melted in front of my eyes and when I arranged to meet him she was beside herself.”

According to Cher, her mom whispered to her as she left for her next date, “You have to tell me everything!”

Cher “enjoyed [Beatty’s company]” and went on two more dates with him. But shortly after, she met her future husband and collaborator Sonny Bono, who she was with the last time Beatty called her.

“Do you want to go to dinner?” Cher recalls him asking.

“‘Well, I have a boyfriend,’ I said.” To which Beatty responded, “Okay, do you want to go to lunch?”

“It was so cute and so him,” Cher said.

Of why her mother let her date a man nine years her senior when she was only 15, Cher writes, “Any other mother might have stopped me from meeting up with a man notorious for sleeping with almost every woman he encountered in Hollywood (and New York, and Paris, and London, and Kuala Lumpur). But my childhood was never normal.”
