“It is with profound sorrow that we announce the tragic passing of Michele and Rob Reiner,” Rob and Michele’s loved ones told Variety.

“We ask for privacy during this unbelievably difficult time,” they concluded.

In one of his final interviews, with Piers Morgan in September, the late actor-director made a chilling comment about his kids.

When asked about his favorite movie he’s worked on, Rob replied, “Listen, people have their favorites. [It’s] the cliché, ‘We love all our children, even the bad ones.’”

Nick, notably, has battled drug addiction since his teens and collaborated on a semi-autobiographical film with his dad in 2015 called “Dear Charlie.”

While promoting the project, Nick told the Los Angeles Times that he was “sick of” his struggles amid repeated rehab stints.

“I come from a nice family,” he said. “I’m not supposed to be out there on the streets and in homeless shelters doing all these things.”
