Alexiana Arian Smokoff was reported to be the wife of Mary Cosby’s son, Robert Cosby Jr. The couple married in 2022, but Alexiana filed for divorce in November 2025, and later reports say the divorce was finalized. Mary’s description of their relationship as “toxic” was her opinion, not an established fact about Alexiana.
Who is Alexiana Arian Smokoff?
Alexiana Arian Smokoff is the name reported for the woman who married Robert Cosby Jr., son of The Real Housewives of Salt Lake City cast member Mary Cosby. Public reporting establishes her connection to Robert and the couple’s relationship timeline; it does not establish further biographical details about her.
Why did Mary Cosby call the relationship “toxic”?
In an Entertainment Tonight interview ahead of the fifth season of RHOSLC in October 2024, Mary described the couple’s dynamic this way: “I just think that they’re toxic. They create toxicity when they’re together and it’s not a good mix.” The remark was Mary’s characterization of their relationship, not a verified finding or an objective description of Alexiana. Yahoo Entertainment’s report republished Entertainment Tonight coverage.
Were Alexiana and Robert Jr. still married?
No. Us Weekly reports that Alexiana filed for divorce in November 2025 and that the divorce was finalized before Robert Jr.’s death. That makes “wife” outdated as a present-tense description; she was his wife, and is now reported as his ex-wife.

What is known about their relationship timeline?
- August 2022: Us Weekly reports that Robert Jr. and Alexiana married at a courthouse.
- October 2023: During an RHOSLC episode, Mary confronted her son about marriage rumors. Us Weekly reports that he said he had gone to the courthouse.
- 2024: Mary spoke about getting used to Alexiana and later described the couple’s relationship as “toxic” in an interview.
- November 2025: Alexiana filed for divorce; later coverage says the divorce was finalized.
- February 2026: Robert Jr. died at age 23. The Los Angeles Times reported that the medical examiner was investigating the cause of death at the time of its report.
Us Weekly’s relationship timeline and legal coverage and the Los Angeles Times report published February 25, 2026 provide the dated accounts. The Los Angeles Times report did not establish a confirmed cause of death.
What should readers make of later comments and allegations?
Mary was also quoted in 2025 as saying, “I still don’t believe she’s his wife,” and expressing doubt about the marriage. That was her stated view, not evidence that the marriage had not taken place; reporting documented the courthouse marriage and later divorce proceedings.

Coverage has also described allegations concerning a reported 2024 incident, which Robert Jr. denied, and guilty pleas to charges arising from separate incidents in 2025. These are distinct matters: an allegation and denial should not be presented as a proven finding, nor conflated with the later legal outcomes. Us Weekly’s account distinguishes the reported allegations, denial and separate proceedings.
