Mary Cosby Mourns the Loss of Her Son, Robert Cosby Jr.
“Real Housewives of Salt Lake City” star Mary Cosby is grieving the heartbreaking loss of her son, Robert Cosby Jr., who passed away at the young age of 23. The tragic news was confirmed by the Salt Lake City Police Department on Monday evening.
Details of Robert Cosby Jr.’s Passing
According to a spokesperson for the Salt Lake City Police Department, officers responded to a call regarding a possible overdose, which ultimately led to a death investigation. While details remain limited, the incident has sent shockwaves through the reality TV community and beyond. A representative for Mary Cosby has yet to release an official statement.
A Brief Marriage and Recent Challenges
Robert’s passing comes just months after his estranged wife, Alexiana Smokoff, filed for divorce. The couple reportedly married in a quiet courthouse ceremony in Utah in August 2022, keeping their union a secret from Mary Cosby initially. Their relationship and struggles were featured on Season 4 of “RHOSLC”, offering viewers a glimpse into their personal lives.
The Bravo show also brought attention to allegations of drug use involving Robert and Alexiana. This, coupled with legal troubles, painted a picture of a young man facing significant challenges.
Past Legal Issues and Family Concerns
Robert Cosby Jr. had a history of run-ins with the law, a topic Mary Cosby addressed during the Season 6 “RHOSLC” reunion in January. She emotionally revealed that her son was arrested and incarcerated for allegedly violating a restraining order filed by Alexiana’s family.
“Her family filed a restraining order against him, and he went back anyway, thinking that she wanted him to come back and save her,” Mary shared, expressing her concern over what she described as her son’s “delusional” state. At the time, Bravo host Andy Cohen revealed Robert’s sentencing was scheduled for February 2026.
