If you’ve spent any time on Bravo-related social media lately, you’ve probably seen the name Robert Cosby Jr. popping up in some pretty intense contexts. The son of Real Housewives of Salt Lake City (RHOSLC) star Mary Cosby, Robert Jr. has gone from a quiet background figure in a lavish Utah mansion to a central, often controversial figure in the show's later seasons. Naturally, fans want to find him online. They want to see the "real" him away from the Bravo cameras.
But finding the official Robert Cosby Jr Instagram isn't as straightforward as it used to be. Honestly, the account has become a bit of a digital ghost town, or worse, a flashpoint for some very public struggles.
Where is Robert Cosby Jr on Instagram?
Finding him is kinda tricky. He has historically used the handle @robert_cosby_, but don't expect a polished influencer feed. Unlike most "Bravolebrities" who use their platforms to sell skinny tea or skincare, Robert Jr.’s presence has been sporadic.
Actually, it's been downright erratic.
Over the last couple of years, his stories have been the primary source of news for concerned (and sometimes prying) fans. In early 2025, for example, he used his Instagram stories to post a black screen with white text, basically telling everyone that his sobriety was none of their business. It was raw. It was aggressive. It was a far cry from the "spoiled" kid image early seasons of RHOSLC painted of him.

The Problem with "Following" Robert Jr.
Here is the thing about his social media: it often serves as a window into his mental state during very difficult times. He has been incredibly open—sometimes arguably too open—about his struggles with addiction.
He's mentioned using:
- Heroin
- Xanax
- OxyContin
- Cocaine
When a reality star's son is posting about these things, the comment sections usually turn into a mess. You have people genuinely praying for him and others just there for the "car crash" appeal. It's a lot for anyone to handle, let alone someone with the added layer of being on the autism spectrum, which his mother has discussed in recent updates.
Why the Account Went Dark Recently
If you go looking for him right now, in early 2026, you won't find much. Why? Because Robert Cosby Jr. is currently incarcerated.

On November 25, 2025, Robert Jr. pleaded guilty to eight charges in a Salt Lake County District Court. These weren't minor infractions. We are talking about:
- Felony property damage (over $5,000).
- Assault on a peace officer (he reportedly bit an officer).
- Violating a pretrial protective order.
- Criminal trespassing.
The legal drama didn't just happen in a vacuum. It was tied to the breakdown of his marriage to Alexiana Arian Smokoff. They got married in secret back in 2022, a plot point that completely blindsided Mary Cosby on the show. By late 2025, the relationship had turned volatile. Alexiana filed for divorce on November 24, just one day before his guilty plea.
His lawyer, Clayton Simms, noted that Robert was "slow to recognize" the marriage was over. He kept trying to reach out, which led to the restraining order violations.
Mary Cosby’s Reaction to the Digital Noise
Mary is, well, Mary. She’s polarizing. Some viewers find her cold; others think she’s just setting boundaries. During the RHOSLC Season 6 reunion filming in early 2026, she made it clear she isn’t visiting him in jail.

She told Andy Cohen that she'd rather have him in jail than dead. It sounds harsh, but when you consider his history of addiction and suicidal ideation, you can see where she’s coming from. She knows that in jail, he isn't using.
He’s expected to remain in the Salt Lake County Jail until his sentencing on February 3, 2026. Until then, don't expect any "Life Lately" posts or gym selfies.
What This Means for Fans
If you're following a "Robert Cosby Jr" account right now that is actively posting, be careful. It’s likely a fan page or, worse, a fake account. The real Robert Jr. is currently cut off from the digital world.
There was a time when his Instagram was a place for him to share his "supposed" wife and their life together in Mary's home. Those posts are mostly gone or buried. The narrative has shifted from a kid living in his mom's basement to a 23-year-old man facing serious adult consequences.
Actionable Insights for Concerned Viewers
It's easy to get sucked into the drama of a reality TV family, but the Robert Cosby Jr. situation is a reminder that there are real people behind the handles.
- Verify the Handle: Don't interact with accounts claiming to be him while he's incarcerated; they are almost certainly fake.
- Respect Boundaries: If and when he does return to social media, remember that he has been vocal about "personal space" and the toll that invasive DMs take on his mental health.
- Support Resources: If his story of addiction resonates with you or someone you know, use the resources he’s indirectly highlighted. The National Domestic Violence Hotline (1-800-799-7233) and addiction recovery centers are better places to direct energy than a comment section.
- Watch the Reunion: The most accurate updates on his status are currently coming through official Bravo channels (like the Season 6 reunion) rather than his personal social media pages.
Robert's journey is a "hardcore road," as Mary puts it. Whether he uses Instagram as a tool for his recovery or leaves it behind entirely remains to be seen once he is released later in 2026.
