Robert Cosby Jr. is basically the enigma of Salt Lake City. If you've scrolled through his Instagram lately, you've probably noticed it's a ghost town. Or a crime scene, depending on how you look at the digital trail he’s left behind over the last few years. While his mother, Mary Cosby, is busy delivering eccentric one-liners on The Real Housewives of Salt Lake City, Robert Jr. has been living a reality that is significantly darker than anything Bravo usually captures in high definition.
Most people think his social media is just another rich kid's playground. They’re wrong.
It was actually the smoking gun. For a long time, fans and amateur sleuths used the Robert Cosby Jr. Instagram feed like a police scanner. Before the show ever admitted he had a problem, his posts were screaming it. We aren't just talking about a little bit of weed or some party vibes. We’re talking about photos of Xanax bars laid out on tongues, bottles of prescription-strength codeine, and even firearms. It was wild. Honestly, it was heartbreaking to watch in real-time.
The Instagram Trail That Blew the Lid Off
Social media is usually a highlight reel, but for Robert Jr., it was more of a cry for help. Back in 2023, while Mary was telling the world her son was "doing great," his Instagram stories told a different story. You’d see a photo of him looking glazed over, surrounded by what looked like a pharmacy’s worth of pills.
Then came the guns.
Seeing a young man in a multi-million dollar mansion posting photos with weapons and "lean" (a mix of codeine and soda) felt like watching a train wreck in slow motion. It wasn't just the fans who noticed. Prosecutors and law enforcement were likely watching too. You've got to wonder what goes through someone's head when they post evidence of a felony to thousands of followers. Maybe when you're that deep in a substance-induced fog, the "delete" button doesn't exist.
What happened to his account?
If you go looking for @robert_cosby_jr today, you’re mostly going to find dead ends or fan pages. He’s scrubbed most of it. Why? Well, probably because he’s spent the better part of late 2025 and early 2026 in the Salt Lake County Jail.

The Marriage Nobody Saw Coming (Except Instagram)
Remember when Mary Cosby "found out" Robert Jr. was married on camera? That was one of those "only on Bravo" moments. But here’s the kicker: the internet already knew.
He had been posting his wife, Alexiana Arian Smokoff, for months. They reportedly tied the knot in a secret courthouse ceremony back in August 2022. For a year, they lived in Mary’s house, basically hiding in plain sight. It’s kinda crazy to think you can live in a mansion with your parents and keep a whole spouse secret, but that’s the Cosby family dynamic for you.
- The Secret Wedding: August 2022.
- The Big Reveal: Season 4 of RHOSLC.
- The Divorce: Filed by Alexiana in November 2025.
The marriage wasn't the fairytale Mary hoped for. In fact, it turned into a legal nightmare. By the time 2026 rolled around, Alexiana had filed for divorce and obtained protective orders. The Instagram posts of them together—once filled with "ride or die" captions—were replaced by court documents alleging assault and trespassing.
A Timeline of the Downward Spiral
It’s easy to get lost in the "he said, she said" of reality TV. Let’s look at the hard facts of what’s been happening with Robert Jr. while the cameras were—and weren't—rolling.
Early 2022: Robert Jr. is arrested for a DUI. He’s caught driving without a license and allegedly tossing beer cans out of the window. Classy.

Summer 2024: After a very uncomfortable on-camera intervention where he admits to using everything from Xanax to Heroin, he heads to rehab. Mary goes on Watch What Happens Live and tells Andy Cohen he’s a "new person."
September 2025: Things fall apart. Again. He’s arrested for trying to break into his father-in-law’s house. According to police reports, he tried to crawl through a dog door.
November 2025: He’s back in jail. This time, he violated protective orders and allegedly bit a police officer. Not exactly the "new person" his mom promised.
February 2026: This is the big one. Robert Jr. is currently scheduled for sentencing. He pleaded guilty to eight charges, including assault and trespassing.
Why the "Perfect Child" Narrative Failed
Mary Cosby often talks about how Robert was a "straight-A student" and the "perfect child." It’s a classic story of a mother in denial. She blames herself for "missing the mark," but the reality is likely more complex.
Living in that house, with the history of the church and the... let's say unconventional marriage between his parents (Mary married her step-grandfather, let’s not forget), had to have an impact. Robert Jr. once told his mother that life felt like "chicken without seasoning" unless he was high. That’s a heavy thing for a 20-year-old to say.

The Robert Cosby Jr. Instagram was the only place he seemed to feel like he could express his "seasoning," even if it was destructive. He wanted to be a rapper. He wanted to be a "boss." But he was trapped in a cycle of wealth and addiction that he couldn't navigate.
The Reality of Recovery in 2026
So, where is he now? As of mid-January 2026, Robert Jr. is behind bars. He’s waiting to find out how much more time he’ll have to serve. His wife is gone. His father, Robert Sr., is reportedly in Las Vegas, and Mary is still trying to manage the fallout on national television.
Recovery isn't a straight line. It’s a jagged, messy, "hardcore road," as Mary put it in a recent interview. The problem with being a "Bravolebrity" child is that your lowest moments are indexed by Google forever. Every time he tries to start over, someone is going to search for those Instagram photos of him with the Xanax bars.
Actionable Takeaways from the Robert Cosby Jr. Saga
If there’s anything to learn from this mess, it’s about the intersection of mental health and social media.
- Social media is a signal: If someone’s posting drastically different or "darker" content, it’s rarely just a phase. It's a data point.
- Wealth isn't a shield: Money clearly didn't solve Robert Jr.'s problems; in many ways, it funded them.
- Legal consequences are real: Even with expensive lawyers, you can't bite a cop and expect to go home for dinner.
- Privacy matters: If you’re struggling, the worst place to be is on a reality TV show.
The saga of Robert Cosby Jr. is far from over. Whether he can actually find sobriety after his release in 2026 remains to be seen. For now, his Instagram remains a digital graveyard of a life that spiraled out of control while the world watched.
