Rob Reiner’s troubled son Nick has reportedly been placed on suicide watch after his arrest for allegedly stabbing the famed director and his wife to death inside their California home.

Nick Reiner is currently being held in administrative segregation and on suicide watch while behind bars at Twin Towers Correctional Facility in Los Angeles, law enforcement sources told TMZ.

Reiner, 32, was arrested on murder charges and is being held without bail after cops found the “The Princess Bride” director and his wife, Michele, stabbed to death in their Brentwood home on Sunday afternoon.

The son of the legendary director has been in and out of rehab for his drug addiction and has faced mental health struggles over the years.

Rob Reiner’s drug-addicted son Nick hacked his beloved director dad and mom Michele to death after a massive blow-up at Conan O’Brien’s Christmas party Saturday — where the nepo baby “freaked out” everyone and left Reiner terrified of what he might do next, pals said.

The trio reportedly ended up in a “very loud argument’’ — possibly because Nick was back on drugs and refusing yet another go at treatment after at least 17 stints in rehab since age 15, sources told The Post on Monday.

“Nick was freaking everyone out, acting crazy, kept asking people if they were famous,’’ a source told People magazine.

The embarrassingly bitter blowout occurred fewer than 24 hours before Nick allegedly fatally slit his parents’ throats in the family’s Los Angeles mansion.

The shocking double homicide of Hollywood legend Rob Reiner and his wife, Michele, has stunned the entertainment world, but for those close to the family, it marked the tragic end of a long-running nightmare driven by their son Nick Reiner’s mental illness and addiction.

Nick was thought to be using drugs again, and his parents feared for his mental state over the past few months, a family friend who has known Nick his entire life told The Post.

“Rob had been telling people that they’re scared for Nick and scared that his mental state was deteriorating. These poor people did everything to help this kid,” the friend, who lives a few blocks away from the Reiner home, said.

The tension between Nick and his parents apparently boiled over just 24 hours before Rob and Michele were reportedly found with their throat’s slashed. Rob and Nick got into some sort of fight at a holiday party hosted by Conan O’Brien Saturday night, the source confirmed to The Post.

Famed author Stephen King took to X on Monday to pen a heartfelt message to Rob Reiner less than a day after he and his wife, Michele, were fatally stabbed in their Los Angeles home.

“I’m horrified and saddened by the death of Rob Reiner and Michele,” King wrote. “Wonderful friend, political ally, and brilliant filmmaker (including 2 of mine). Rest in peace, Rob. You always stood by me.”

Reiner adapted two of the writer's books for the big screen -- “Stand by Me” is based on King's “The Body,” and “Misery,” which won an Academy Award in 1991.

Rob Reiner's troubled son, Nick, is being charged with murder for the stabbing and is currently in custody on $4 million bail.

Nick Reiner revealed that he once “destroyed” parents Rob and Michele Reiner’s home during a drug-fueled rage.

In a 2018 appearance on the “Dopey” podcast, Nick recalled a time when he became violent while being “sequestered” in the famed director and actress’ guest house while he was high “on meth.”

“I went 10 rounds in my guest house,” he shared.

“It’s not much of a story. I got totally spun out on uppers — I think it was coke and something else — and I was up for days on end,” Nick, 32, added. “I started punching out some things in my guest house.”
