“Real Housewives of Salt Lake City” star Mary Cosby’s son, Robert Cosby Jr., has died. He was 23.
A Salt Lake City Police Department spokesperson confirmed to Page Six that Robert was found dead on Monday evening after officers “responded to an overdose call that turned into a death investigation.”
A rep for Mary wasn’t immediately available to Page Six for comment.
Robert died after his estranged wife, Alexiana Smokoff, filed for divorce a few months ago.
The exes reportedly tied the knot at a courthouse in Utah in August 2022, and their marriage was a storyline in Season 4 of “RHOSLC” after they kept their nuptials a secret from Mary.
The Bravo show also shed light on Robert and Alexiana’s alleged drug use, including during Season 6, which was filmed in early 2025.
Robert also had a history of run-ins with the law, which Mary shed light on during the Season 6 “RHOSLC” reunion in January.
During the episode, the Bravolebrity emotionally revealed that her son was arrested and serving time in jail after allegedly violating a restraining order put in place by Alexiana’s family.
“[Her family] filed a restraining order against him, and he went back anyway, thinking that she want[ed] him to come back and save her,” Mary said. “I don’t know where he’s getting that from … delusional.”
At the time, Bravo head honcho, Andy Cohen, shared that Robert’s sentencing was scheduled for February 2026.
“I’m not worried about him,” Mary said, while visibly upset. “I know he’s somewhere where he’s not using.
“At some point, I have to step back so that he can learn and he can make his own decisions, and unfortunately, he’s learning the hard way. But I’m OK with it.
“It’s just, you don’t want to see your kid suffer, but I know it’s good,” she added. “And I’d rather him be there than dead, you know?”
Mary shared that she refused to go visit Robert in jail and look at him from behind the glass.
However, she ensured viewers that she and Robert talked every day on the phone and her husband, Robert Cosby Sr., was sending him “a lot of books.”
