Rob Reiner and son Nick argued at holiday party hours before deaths: reports

The Reiner family attended a holiday party at the home of Conan O'Brien, where Nick reportedly 'alarmed the guests with his behaviour.'

Rob Reiner and Michele Singer Reiner got into a “very loud argument” with their son Nick at a party Saturday night, just hours before the director and his wife were found dead, according to multiple sources.

The Reiner family attended a holiday party at the home of Conan O’Brien, where Nick reportedly “alarmed the guests with his behaviour,” according to two attendees who spoke to The New York Times.

Rob and Nick, 32, reportedly got “into a shouting match at the party in West Los Angeles,” one of the attendees said, who asked not to be named.

According to the source, Rob told Nick that his “behaviour was inappropriate.” The attendee added that people at the party “seemed to be very aware of Nick Reiner’s history with drug abuse.”

Another partygoer said that he and other people at the party “were worried” and that “several people commented to him on Nick Reiner’s behaviour, saying he looked anxious and uncomfortable in a way that deeply unsettled them.”

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

Another person said Nick’s parents were “upset and embarrassed about their son’s behaviour at the party and expressed worries about his health,” NBC News reported.

Nick is alleged to have interrupted a conversation involving comedian Bill Hader. When Hader told him the conversation was “private,” Nick “appeared to stand still and stare before storming off,” one person told NBC News.
