Ryan O’Neal’s daughter, Tatum O’Neal, said the house her late father shared with actress Farrah Fawcett has burned down in the horrific LA fires.

“It’s the saddest ever, so sad I could cry,” the Oscar winner, 61, wrote on Threads Saturday. “My father’s house is gone Malibu gone.”

Tatum, who starred opposite her father in the hit 1973 film “Paper Moon,” later responded to a thread about the fire damage.

“Gone gone gone gone. It’s so scary. I am so freaking sad,” she added in a follow-up post about the home.

Damage to the Hollywood star’s home comes after he died from congestive heart failure at 82 in December 2023.

Fawcett died in 2009 at 62 following a battle with cancer.

While the pair never tied the knot during their on-again, off-again relationship, which started in 1979, they lived together in the plush beachfront home for many years.

Following Ryan’s death, sources told The Post that the actor left behind a $30 million estate.

The estate included the $5 million Malibu beachfront home, which he bought in 1976 for just $151,000, as well as an Andy Warhol portrait of Fawcett he fought to keep.

Tatum’s relationship with her late father was not always smooth.

The actress was estranged from Ryan for about 20 years before reconciling after Fawcett’s death.

She then co-starred with her father in a brutally frank 2011 reality show called “Ryan and Tatum: The O’Neals” on Oprah Winfrey’s OWN network.

In her scathing 2005 memoir, “A Paper Life,” Tatum eviscerated her father in part, claiming he had been abusive to her, Fawcett and others — but she also made it clear that she always loved him.

Tatum had a stroke following a drug overdose in 2020 but reunited with her father twice after that, including visiting him in Malibu for his birthday in April 2023.

The late actor’s home is just one of the tens of thousands that has been reduced to rubble following the still-raging Los Angeles wildfires.

As of Monday morning, the death toll has risen to 24 with at least 16 still missing, according to an update from the Los Angeles County Medical Examiner.

The majority of the victims — 16 — were killed in the Eaton Fire, while eight were killed by the Palisades Fire — the two largest of the fires devouring the county.

With the new death toll, the Eaton Fire is now the fifth-deadliest wildfire in California’s history.

About 150,000 people in Los Angeles County remained under evacuation orders Sunday and more than 700 residents are taking refuge in nine shelters, Los Angeles County Sheriff Robert Luna said.
