Cher looks back on her second marriage – and what went wrong.

The singer reflected on her relationship with Gregg Allman and why she said “yes” so quickly in her best-selling book Cher: The Memoir, Part One.

According to the book, Cher’s divorce from her ex-husband Sonny Bono was finalized in June 1975, when she had already started dating the rocker.

The now 78-year-old admitted she had some reservations about her blossoming romance with the Allman Brothers Band singer.

CHER CONFESSES THAT THE SONY-BONO MARRIAGE DRIVEN HER TO THOUGHTS OF MURDER AND SUICIDE IN THE DARKEST MOMENTS

“I didn’t know whether my relationship with Gregory would last or not,” the star wrote, as quoted by People magazine on Wednesday.

“I lived each day as it came,” she said. “Then I found out I was pregnant and we decided to get married.”

According to the outlet, Cher wanted to get married if she had a baby.

“I kept putting one foot in front of the other,” Cher wrote, as quoted by the magazine. “The future is never set in stone. I did what I thought was right.”

The book states that Cher’s sister Georganne “Gee” and her friend Paulette looked at the singer “as if I had gone to an alternate universe” after telling them she was ready to tie the knot. In response, Cher said, “Come on, let’s just do this.”

The outlet noted that the wedding took place days after Cher’s divorce from Bono.

“There was nothing romantic about our wedding day,” the Oscar winner admitted.

Nine days after her wedding, Cher filed for dissolution of the marriage. They reconciled.

The couple had a son, Elijah Blue Allman, in 1976. However, they finally separated in 1979.

The New York Post previously reported that the “Believe” singer originally filed for divorce after she allegedly found a “plastic bag full of white powder” that belonged to her spouse.

Things only got worse when she later learned that Allman had a crippling heroin addiction.

“(I) told him on the phone, ‘I’m just so tired of doing this, Gregory. I’m so tired of going to rehab with you,'” she recalled as quoted by the outlet. “He was silent on the other end of the line. ‘But I’ll carry on,’ he said quietly.”

“His answer amazed me because it was true,” Cher continued. “He kept going to rehab, kept trying to get clean, kept trying even though he had failed in the past. Instead of thinking about my own exhaustion, I was able to empathize with him in that moment.”

Cher wrote that her “breaking point” came after Allman suffered “a paranoid breakdown” one night.

“(He) insisted he saw men with guns in the backyard,” the Grammy winner wrote.

She called that moment “the final straw that broke the camel’s back.”

“It wasn’t safe for the kids,” Cher said. “It only happened once, but I couldn’t risk it.”

The “I’m No Angel” singer died of liver cancer in 2017. He was 69.

Alan Paul, author of “Brothers and Sisters: The Allman Brothers Band and the Inside Story of the Album That Defined the 70s,” previously told Fox News Digital that the late star “never stopped loving Cher.”

“Gregg didn’t like to talk about Cher,” Paul said. “People took that to mean that she didn’t like her, that she was aggressive towards her or something like that. I don’t think that was ever the case. I think it was the opposite.”

Paul said that looking at their marriage, it was clear that neither of them were prepared for what was to come.

“Gregg was a full-blown drug addict at the time and was struggling to cope,” he explained. “He went in and out of rehab several times. There were times when he managed to cope. He spoke about it very openly. Cher, even though she had been in Hollywood since she was 16 or 17 and was a celebrity, was pretty naive. She didn’t understand what that meant.

“At some point, early in their relationship, Gregg tells her, ‘Just go home. Imagine this is a trip to Disneyland. It was fun while it lasted. Now go home,’” Paul said. “He couldn’t bring himself to tell her he was an addict. Cher is completely devastated, angry, overwhelmed. In her mind, everything is going great. She’s basically wondering, ‘What the hell is going on?'”

Paul claimed Allman “cried for almost an hour” before he could muster the courage to tell her, “I’m a junkie.”

“The good news is that I’m madly in love with you, but the bad news is that I have a problem,” he told her.

An “unbothered” Cher reportedly said: “That’s fine – we can do it.”

“You don’t understand,” he pleaded. “I would steal your mom’s TV.”

Paul claimed Cher was confident it was an obstacle they could overcome together.

“Their reaction was, ‘That’s OK, it’s a problem and we’re going to fix it,'” he explained. “She understood it as a problem, but she thought it was something where you go to the doctor, you can go to rehab and it will get better. She didn’t understand… And Gregg was so open about it… From the very beginning of their relationship, she was overshadowed by his drug use.

Part two of Cher’s memoir is scheduled to be published in 2025.
