Hugh Hefner son: I did not get my full inheritance after will changed — while dad was ‘incoherent’

One of Hugh Hefner’s sons alleges that his father’s will was changed while the Playboy founder, who died at 91, was “incoherent” — and that his inheritance was reduced.

“From my understanding, I did not receive all the funds meant to go to me in terms of what my dad wanted me to get,” Marston Hefner, who earns money on OnlyFans, told The Post.

In the year leading up to the 2017 death of Hugh Hefner, his notoriously free-spirited Playboy Mansion took on a somber air.

“The Mansion became a lot more empty — it was sad,” Marston told The Post.

“People who used to visit weren’t visiting. He didn’t go down the stairs. It was a different atmosphere,” recalled the 34-year-old, who is one of Hef’s two sons with Playmate ex-wife Kimberly. “He started going on pain medication because of his bad back. There was no restriction on how much medicine he could take. He was incoherent.”

Behind the scenes, he alleged, questionable changes were being made to his father’s finances.

“The year that he passed away, he changed the will,” Marston recently said on the podcast “Girls Next Level,”which is hosted by his dad’s onetime girlfriends Holly Madison and Bridget Marquardt.

“And nobody f–king knew that the will was being changed until [after] he passed away. I did not know the will was changed until we received the will,” he told The Post.

Covering this topic on the podcast, Marston said,“I was like, ‘Why? When he didn’t know what was up or down half of the time, why would he change his will?'”

He alleged to Madison and Marquardt that the revisions meant that Crystal Harris — his stepmother, who married Hef in 2012 and who he called “a master manipulator” in a text message to the podcast hosts — got paid first: “The first person who got the money, in my opinion, if I remember it, was Crystal.”

But now, Marston said to The Post,“I am not sure if [her getting the money first] is accurate … I don’t know who changed the will.”

When asked about the timing of the purported changes and who they may have benefited, Crystal Harris told The Post, “This story is untrue and was discredited by Hef’s estate attorney who wrote his will years before Hef passed.”

Marston, however, said he remembered that the will was changed.

“My memory is that the change was made within a year before his passing. This was an addition, not a changing of the previous planning,” he claimed.

Marston added, “I was upset. When they were explaining the inheritance and how it would work, I was baffled. I didn’t understand.”

At any rate, the money that was in in Hugh Hefner’s estate was not insubstantial.

According to the Daily Mail, Crystal had signed a prenup that left her with $5 million cash and a home worth some $7 million at the time of 91-year-old Hugh Hefner’s passing.

Beyond that, he left behind a $43 million estate that was to be shared by his four children — Cooper, 32; Marston, Christie, 71; and David, 68 — as well as Hef’s alma mater, the University of Southern California, and assorted charities.

At the time of Hef’s death, according to a “back of the envelope” calculation in Fortune magazine, he would have had a net worth between $15 million and $26 million.

Though he feels that he could have come out better in terms of his inheritance, Marston emphasized that he harbors no bitterness.

“There is nothing I can do. I’m happy with what I got,” said Marston, who shares a 10-month-old son, Forrest, with wife Anna Lambropoulos. “I’m grateful to be in a financially secure situation. I can provide for my family and have a blessed life. I don’t have hard feelings and resentment. I just want to put out how I feel.”

Lambropoulos previously told Page Six that she “die[d] inside” after finding out that Marston spent $100,000 of his OnlyFans earnings on two Pokémon cards and a collectible comic book.

Marston told The Post this week that he’d had a complicated relationship with his father, who founded Playboy Enterprises in 1953.

“We were close. He hugged me and said he loved me,” he said. “But my opinion is that he was not close or affectionate to most people. I lived next door. I visited. I played Backgammon every Sunday. There was a wall between him and everyone else, including me.”

One thing that brought them together was Backgammon. Even as Hef’s final months neared, according to Marston, Backgammon remained a bonding agent; but the tenor of the game, which Hef had long obsessed over, had changed.

“We would play, and my dad would not know the moves to make,” said Marston, explaining that it said a lot about his father’s decline. “He knew Backgammon better than his ABCs. In my opinion, he was compromised. If he didn’t know where he was or what game he was playing, why was he changing his will?”
