Conan O’Brien stopped a friend from calling 911 during an explosive fight between Rob and Nick Reiner at the comedian’s Christmas party – just hours before the director’s son allegedly cut his parents’ throats, guests have revealed.
Multiple attendees have reported witnessing Rob, 78, and wife Michele, 70, having a heated argument with 32-year-old Nick at O’Brien’s Los Angeles mansion on Saturday night.
Nick is said to have been behaving erratically all evening, but one source familiar with the party has now told the Daily Mail the spat grew so intense that at least one guest suggested calling the cops to intervene.
‘They got in an argument, the father and son. It got so bad and loud someone wanted to call the police to report it,’ the insider claimed.
‘But Conan stepped in and said, “it’s my house, my party, I’m not calling the police.” He talked them out of calling the police.’
O’Brien, 62, did not respond to the Daily Mail’s requests for comment.
Another source corroborated the account, saying party guests had raised concerns about Nick’s mental state and suggested contacting the cops before O’Brien shut the idea down.
‘When the s**t was hitting the fan, somebody said we need to call the police. The conversation was about getting this kid put into a mental-health hold,’ the second source told the Daily Mail.

‘Conan O’Brien stepped in and said, “no, I don’t want the police at my house”. It makes sense; who wants the cops showing up creating a scene?’ the insider added.
‘But the argument between Rob and Nick was pretty intense.’
A source close to the Los Angeles Police Department said there were no 911 calls from O’Brien’s house on Saturday night.
And despite partygoers’ concerns, nobody predicted what would happen next: that Rob and Michele Reiner would be found dead from knife wounds less than 24 hours later.
‘Only the murderer is responsible,’ the first source said.
‘But it must be gut-wrenching for Conan to learn that this is how things turned out. I’m sure that night is replaying for him over and over.
‘It’s just so awful and sad.’
In another haunting revelation, the Daily Mail has also learned that Rob Reiner had confided to friends at the O’Brien party about being scared of his own son.
The beloved filmmaker, 78, and his wife Michele Reiner, 70, were found dead at their Brentwood home on Sunday December 14
‘They got in an argument, the father and son. It got so bad and loud someone wanted to call the police to report it,’ one insider claimed. (Pictured: Albert Brooks, O’Brien and Reiner in 2024)
‘I’m petrified of him. I can’t believe I’m going to say this but I’m afraid of my son. I think my own son can hurt me,’ Reiner allegedly said immediately after his altercation with Nick.
Those comments resurfaced at an impromptu memorial attended by Hollywood A-listers on Monday, where the details of the party were discussed, according to a source.
The insider told the Daily Mail that several attendees were left in tears upon hearing what Rob had said.
The Daily Mail contacted representatives for all the stars in attendance at Monday’s impromptu memorial. One spokesman denied that Rob had made the comments about Nick at O’Brien’s party.
TMZ first reported that Reiner had had a ‘very loud argument’ with his son at the holiday party, after which the legendary movie director and his wife left.
The Reiners had reportedly brought Nick to the star-studded event to ‘keep an eye on him.’
Nick had been living in the Reiners’ guesthouse at their Brentwood mansion, after years of substance abuse issues, at least 18 stints in rehab and some periods of homelessness.
Sources have also told TMZ that he was suffering with worsening schizophrenia and became ‘erratic and dangerous’ when doctors changed his medication weeks before the tragedy.
Guests at the A-list packed party say Nick displayed ‘antisocial behavior’, such as staring at attendees and repeatedly ‘asking people if they were famous,’ according to reports.
Nick was in court Wednesday wearing a blue anti-suicide vest, it was his first appearance since the death of his parents. He has been charged with two counts of first-degree murder
A source told NBC News that at one point Nick ‘interrupted’ comedian Bill Hader, who then told Reiner’s son that he was ‘in the middle of a private conversation’ – prompting an angry outburst.
‘Nick just stood there and stared before storming off,’ the witness said.
Hours later, Rob and Michele Reiner were found dead at their home.
Their bodies were discovered on around 3.30pm on Sunday afternoon by their youngest daughter Romy, 27, who lives across the street from her parents’ property.
The couple were found in bed with their throats cut and may have been asleep when they were murdered in the early hours of the morning, a source close to the investigation claimed to the Daily Mail.
Nick, who lived in his parents’ guest house, was arrested around 9pm Sunday night 15 miles away.
He had earlier checked in to The Pierside Santa Monica hotel, where staff reportedly later discovered a shower ‘full of blood’, a trail of blood leading off of his bed and bedsheets covering the windows.
Nick, who has been charged with two counts of first-degree murder, is now being held without bail.
