The private Instagram profile of Nick Reiner has come under scrutiny as he faces charges of first-degree murder for the alleged stabbing deaths of his parents, Rob Reiner and Michele Singer Reiner.

Exclusive images from Nick’s Instagram account have been acquired by Page Six, showcasing a glimpse into his personal life through two previously unseen photographs.

One post, dated November 28, 2017, captures a playful moment where Nick, 32, appears to be jokingly choked by an unidentified man. The post, tagged in Havana, Cuba, includes a caption that reads, “Cuban choke slam.”

Another image from April 28, 2017, features Nick giving a somewhat strained smile as he poses on a bench, clad in a black jacket, jeans, and a cowboy hat.

Despite the serious allegations he faces, Nick’s siblings, Jake, 34, and Romy, 28, have continued to follow him on the social media platform, indicating a familial bond amidst the unfolding drama.

One of Nick’s former co-workers provided the screengrabs of the Instagram profile to Page Six, and also spoke to us about their time working together on the set of “Family Guy” in 2014.

“He was an intern on the show ‘Family Guy’ for around three to six months. His father helped him get the gig,” the insider shared, noting that Rob “would drop him off” and “pick him up” every day.

“He was coming off rehab, so he was sober. This was part of his path to recovery. His whole identity was being sober.”

The source told us that Nick would work four hours a day, but would spend most of his time “shooting the s–t” with his fellow employees.

“He did not work hard and he wasn’t a hard worker,” the insider alleged. “He was 100 percent entitled. There was really no responsibility for him because we didn’t have interns. It was a favor for Rob.”

The source described Nick as “captivating” and “goofy” during his younger years, a contrast to his state of mind leading up to when his parents were murdered.

“His darkness was his humor. He has a dark sense of humor,” the source explained. “He was a funny kid. He was charismatic in a dark, introverted way. He was a goofy 20-year-old.”

The insider told Page Six that Nick would often say “f–ked up things, dark things” with a “tinge” of humor.

“He was the black sheep. He felt like a f–k up. He knew that,” the source continued. “He was self-aware of how his family was doing and how he represented them in a negative space. But none of that felt offensive or scary.”

Despite “liking” Nick, the source explained how he wasn’t surprised when he heard that he had been arrested on charges of murder.

“I am not that shocked. He is a troubled person,” our insider admitted. “Nick had an era of darkness around him with his addiction issues. When you have addiction and mental health, there is room for emotional murders.”

“It doesn’t seem unfounded,” they added. “He was a troubled kid from a young age and had issues. But that’s not the Nick I knew.”

The insider also remembers Rob as the loving, caring father who “tried his best to help Nick get on his feet” over the years.

“He really cared about him. When Nick wanted to get into screenwriting, he had him write a script for ‘Being Charlie,’” they shared.

“They were all very close. They were a close family.”

On Nick’s Facebook page, he has a photo from his time working on “Family Guy.”

He could be seen sitting under a desk, as he captioned the snap, “Havin fun at work.”

Rob, 78, and Michele, 70, were found stabbed to death in their Brentwood home in Los Angeles on Sunday afternoon.

Rob and Michele were reportedly dead for at least several hours, as rigor mortis had appeared to have set in before they were found, TMZ reported.

Sources initially told The Post that Nick was considered a person of interest.

Nick fled the scene and was arrested in connection to the murder later that evening.

He is currently awaiting his Jan. 7, 2026 arraignment in Twin Towers Correctional Facility, where he is being held without bail and is being represented by famed defense lawyer Alan Jackson.

Just hours before the murder, Nick acted bizarrely toward guests at Conan O’Brien’s Christmas party on Dec. 13 — even getting into an argument with his father.

Nick has struggled with drug addiction for years, as he co-wrote the semi-autobiographical 2015 film “Being Charlie” — which was directed by his father — about his nearly 20 stints in rehab.

Nick also has an alleged history of violence, as a neighbor of the Reiner family told The Post, “This is not the first time their son has been violent. I just never thought it would ever get to this point.”
