Robert Cosby Jr., the son of ‘The Real Housewives of Salt Lake City’ star Mary Cosby, has reportedly passed away at the age of 23.
On Wednesday, February 25, TMZ published an exclusive report asserting that on Monday, February 23, Robert Cosby Jr. passed away. Furthermore, the outlet reports that Robert passed away in Utah. Police reportedly responded to reports of a “possible overdose” for a 23-year-old male.
However, once police arrived, the incident turned into a death investigation.
Per the outlet, Robert made a few appearances on’RHOSLC.’ During season 4 of the show, Mary Cosby reportedly learned that he had secretly tied the knot. However, in November 2025, his wife, Alexiana Smokoff, reportedly filed for divorce. It was apparently finalized in January. However, per Page Six, Robert subsequently spent time behind bars for violating his ex-wife’s protective order.
“Hes looking forward to doing positive things. The difficulty is that he was slow to recognize the dissolution of his marriage. But now he understands the relationship is over, and hes moving forward,” his lawyer reportedly stated amid his release and ordered probation, per Page Six.
Additionally, the show also chronicled Robert’s apparent drug addiction. Per Variety, on one occasion, Robert informed his mother of his use of Xanax, Molly, acid, cocaine, and weed over the years.
