Nonetheless, once police arrived, the incident became a death investigation.
Per the outlet, Robert made a number of appearances on’RHOSLC.’ During season 4 of the show, Mary Cosby reportedly learned that he had secretly tied the knot. Nonetheless, in November 2025, his wife, Alexiana Smokoff, reportedly filed for divorce. It was apparently finalized in January. Nonetheless, per Page Six, Robert subsequently hung out behind bars for violating his ex-wife’s protective order.
“He’s looking forward to doing positive things. The problem is that he was slow to acknowledge the dissolution of his marriage. But now he understands the connection is over, and he’s moving forward,” his lawyer reportedly stated amid his release and ordered probation, per Page Six.
Moreover, 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 time.
