Crystal Hefner reveals Hugh’s final words on his deathbed

These bombshells weren’t blond at all.

Hugh Hefner’s widow, Crystal Hefner, has revealed the very “last words” the Playboy magazine publisher said to her on his deathbed on Sept. 27, 2017.

According to Crystal’s brand-new book, “Only Say Good Things: Surviving Playboy and Finding Myself,” the media mogul said, “I’m OK,” as he was being injected with antibiotics through an IV.

While Hugh’s death at 91 had been initially ruled as “natural causes,” Crystal writes, her spouse spent his final days fighting an “aggressive” E. coli infection that was “highly resistant to antibiotics and difficult to treat.”

The former Playboy Playmate, 37, told People magazine that she was never actually “in love” with her late husband.

“At the time I thought I was on top,” she said. “I thought, ‘Wow, if I just like everything that he likes and do all the things that he wants me to do, then I’m the favorite.’ And I was, but I just lost myself in the process,” she said prior to the book’s release Tuesday.

In 2010 — two years after Crystal had moved into the fabled Playboy Mansion with Hugh and his cadre of women — the publisher proposed to the doe-eyed 24-year-old on Christmas Eve.

The gesture left Crystal conflicted over the idea of marriage to the millionaire.

According to her book, she accepted the offer but broke off the engagement just five days before their planned June 2011 wedding.

Crystal told People that she sought companionship with Dr. Phil’s son Jordan McGraw, a man she had previously dated, before ultimately returning to Hugh at the Playboy Mansion.

The “Girls Next Door” star married Hef on Dec. 31, 2012.

“I realized I was dealing with a really big power imbalance,” Crystal said. “It seemed like a world of success and fantasy, but everyone’s having to sleep with an 80-year-old. There’s a price. Everything has a price.”

Her book also details the very regimented lifestyle that was allegedly enforced by Hugh during her stay.

According to the model, Hugh would give each of his “girlfriends” an allowance that he handed to them in neat bills.

“Our nail polish couldn’t be anything but some neutral color, no French manicure,” Crystal added.

The former Playmate of the Month also recalled an instance when Hugh made a scathing remark about how the roots of her natural brown hair were poking through.

“So I’d have to go bleach it and it would burn my scalp and I’d have blisters,” she recounted. “But for some reason, I thought this was all normal and that’s what it meant to be seen as beautiful in Hef’s eyes.”

This past July, Crystal exclusively revealed to The Post the meaning behind the title of her book.

She recalled “a conversation with Hef … He let me know: ‘Once I go, when I’m gone, please only say good things about me.’”

“I kept that promise for the last five years. After going through a lot of therapy and healing, I realized that I needed to be honest about my time there,” she said. “The book is about healing from a toxic environment.”
