Robert Cosby Jr., the 23-year-old son of The Real Housewives of Salt Lake City star Mary Cosby, has died. Salt Lake City police confirmed they responded to an overdose call Monday evening that became a death investigation. A medical examiner is determining the official cause of death. Mary Cosby shared the news publicly, writing that her son “has been called home to the Lord,” adding that while their hearts ache, they take comfort in their faith.
Robert appeared alongside his mother on RHOSLC and, in recent seasons, spoke candidly about his struggles with substance abuse and depression. His on-camera conversations with Mary were among the most vulnerable moments in the franchise, showing a mother and son navigating addiction in real time. In interviews, Mary later said those discussions were unplanned and unfolded naturally as they talked.
Bravo released a statement expressing heartbreak over the loss, calling Mary “a cherished member” of the network’s family. Executive producer Andy Cohen also shared his condolences, describing the situation as “every parent’s worst nightmare.” Cast members and fellow Housewives posted messages of support across social media, surrounding Mary and her family with public expressions of grief.
Robert’s death comes after a period marked by legal issues and efforts toward recovery that were discussed both on and off the show. As tributes continue to pour in, the focus remains on a young life cut short and a family mourning an unimaginable loss.
