Robert Cosby Jr.

Robert Cosby Jr. was the only son of Mary Cosby, an original cast member of Bravo's The Real Housewives of Salt Lake City, and Bishop Robert Cosby Sr. He was not a television personality by trade, but his life became part of the public conversation around the series as viewers followed his mother's storylines about family, faith, and the Salt Lake City Pentecostal church where she serves as first lady.

In recent seasons of RHOSLC, Mary Cosby spoke openly about her concerns for her adult son, including struggles with substance use and encounters with the justice system. Court reporting and entertainment coverage documented a period of legal trouble that included jail time in Salt Lake County, followed by a release in early 2026. His attorney described that period as one that had allowed him to sober up and look ahead. About two weeks before his death, Mary posted a photograph of her son on Instagram with a short, affectionate caption calling him her beautiful son.

Robert Cosby Jr. died on February 23, 2026, in Salt Lake City. He was 23. The Salt Lake City Police Department confirmed to major outlets, including E! News, ABC News, and NBC News, that officers responding to a call for a possible overdose found him dead, and that the medical examiner's investigation into the cause of death was continuing. Mary Cosby and Robert Cosby Sr. issued a statement of faith and grief two days later, saying their beloved son had been called home to the Lord and that they took comfort in knowing he was finally at peace. Bravo and executive producer Andy Cohen publicly expressed condolences.

Later in 2026, during the season seven premiere of The Real Housewives of Salt Lake City, Mary Cosby spoke on camera about mourning her son and described a Homegoing memorial service that celebrated his life. Castmates including Angie Katsanevas and others were shown rallying around her. Coverage of that premiere and of tributes from within the RHOSLC circle renewed public searching for information about Robert Cosby Jr. in September 2026, but his death itself had occurred months earlier, in February.
