Rob Reiner and his wife, Michele Singer Reiner, reportedly dined with Maria Shriver less than 48 hours before their gruesome murders.

The trio is said to have dined at Brentwood, Los Angeles, eatery Amici on Dec. 12, according to restaurant owner Tancredi DeLuca.

“They were very good people, always very approachable and so very kind to the entire staff,” DeLuca told the Daily Mail in an interview published Saturday.

According to the staff, the group dined on the restaurant’s winter special, Sogliola Alla Mugnaia, which is an imported Dover sole served in a lemon-caper sauce, with broccolini and roasted potatoes. They had some pasta with the dish.

Reps for Rob have not responded to Page Six’s repeated requests for comment. A rep for Shriver did not immediately respond to Page Six’s request for comment either.

The famed director and his wife were found stabbed to death inside their Los Angeles home on Dec. 14. Rob was 78. Michele was 70.

Among the list of celebrities who mourned the Hollywood loss, Shriver, 70, also shared a touching tribute to the couple, whom she affectionately referred to as two of her “closest friends.”

“I loved Michele and Rob Reiner,” she wrote via X on Dec. 15. “We raised our kids together, from mommy and me on up. We laughed together, we cried together, we played together, we dreamed together. We had dinner this past week, and they were in the best place in the their lives: loving one another, loving their friends, their family, their country.”

“They never gave up on our country. They wanted to make it better. They always, always wanted to make our world better, and they were willing to fight to make it the country they loved.”

“I’ll miss you, Michele. I’ll miss you, Rob. I love you both. Thank you for your friendship. God bless you both. Life will not be the same without you here, that’s for sure,” she closed her lengthy message.

As previously reported, Rob and Michele were last seen alive at Conan O’Brien’s holiday party on Dec. 13, where they allegedly got into a heated argument with their son, Nick, sources told The Post.

Multiple outlets reported that Nick, who has publicly struggled with drug addiction, behaved erratically at the party, disturbing the other A-list guests including comedian Bill Hader.

At one point, a source familiar with the event claimed that Nick’s behavior had several guests looking to call the police on him. Though, they were stopped by party host O’Brien.

“They got in an argument, the father and son. It got so bad and loud [that] someone wanted to call the police to report it,” an insider told the Daily Mail on Friday. “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.”

it was also reported that Rob shockingly told close friends at the party he was “petrified” that his son could “hurt” him in his last words at the event following the massive blowup.

Sources later told The Post that the couple’s slain bodies were discovered on Sunday by their daughter Romy Reiner.

The pair were found with stab wounds to their throats among multiple wounds found throughout their bodies. Their official causes of death were listed as “multiple sharp force injuries.”

Nick was arrested later that evening and has since been charged with two counts of first-degree murder for the deaths of his parents. In his first court appearance on Wednesday, he received a Jan. 7, 2026, arraignment date.
