Hugh Hefner's son accuses Crystal Hefner of being a 'master manipulator' who was focused on power

The son of Playboy mogul Hugh Hefner has hit out at his father's widow, Crystal Hefner.

Marston Hefner made a series of explosive allegations against Crystal in an appearance on the Girls Next Level podcast, even calling her a 'master manipulator'.

The 34-year-old also claimed that Crystal had overseen changes to his father's will when he was not of sound mind.

Among the allegations was that Crystal had become hooked on the 'idea of control and power', including keeping a tight grip on who was and wasn't allowed on guest lists.

Marston said when speaking to hosts Holly Madison and Bridget Marquardt: "She liked controlling the guest list. She liked taking girls off and on the guest list depending on how, whatever the whims were at the time…

"She liked being in that position where you had to go through her or you had to ask her for things."

He also claimed that 'tribes' had formed in the mansion, saying: "When Crystal came in [to the mansion], there started to be tribes. And so there were people who were on Crystal's team."

But perhaps most explosive was Marston's allegation that Crystal had overseen alterations to Hefner's will when he was taking medication for back pain.

Marston claimed that his dad had forgotten how to play backgammon and that he was 'sick' and 'dosed with f*cking medication.'

"He was really sick and that's why she got all these NDA things," Marston said. "According to her, she didn't want people to see him not able to walk, not able to talk."

Marston explained: "The year that he passed away, he changed the will and he gave me, another person, and Crystal more money. And I don't know how much more, I don't remember if Crystal got more than us...."

Marston went on to question why his father would change his will, and claimed that Hefner was not of sound mind during this period.

He said: "I was looking at that when I was getting the inheritance, and I was like, 'Why? When he wasn't here, when he didn't know what the f**k was up or down half of the time, why would he change his will?'"

Marston went on to say that he had sent an email saying that he didn't think his late father was 'competent' anymore.

However, he claimed that "nobody really wanted to address what I perceived as the elephant in the room."

Hefner married Crystal in 2021 when he was 86 and she was 26. The pair remained married until Hefner's death in 2017 at the age of 91.
