Robert Cosby Jr., the only son of Real Housewives of Salt Lake City star Mary Cosby, has died at age 23, authorities have confirmed. Prior to his passing, Mary was candid about her son’s struggle with substance abuse. During season five of the Bravo show, the pastor confided in costar Angie Katsanevas about her personal family problems, revealing the moment Robert Jr. shared he was becoming addicted. She recounted him telling her, "’And then I started trying other stuff and then I tried other stuff.’ And then at some point he said it almost became an addiction." She continued, "I said 'Not almost,’ and he's like 'Yeah. Yeah, it's addiction, mom.'" Following his arrest in November 2025, Mary addressed his incarceration during the RHOSLC season seven reunion earlier this month. She shared at the time, “Unfortunately he's learning the hard way, but I'm okay with it. It’s just, you don’t wanna see your kid suffer, but I know it’s good.” Full Story: eonline.com/news/1428985/andy...
