RHOSLC: Mary Cosby’s Son Posts Drug Use on Social Media

RHOSLC OG Mary Cosby in her confessional interview

Robert Cosby Jr, the son of RHOSLC star Mary Cosby, has been spotted along with his wife, Alexiana, flaunting their drug use on social media.

It seems that a lot of shady shit may be going down inside Mary Cosby‘s Utah mansion right under her nose.

Robert Cosby Jr., 20, and his wife, Alexiana Cosby, reportedly still live in Mary’s mansion, which has been heavily featured on RHOSLC. On social media, both Robert Jr and Alexiana have shared multiple posts featuring various drugs, including marijuana, prescription codeine syrup, and unidentified pills.

In dozens of photos and images, Robert can be seen posing alongside “codeine prescription bottles, promethazine hydrochloride cough syrup and/or bottles and cups of a ‘purple drink.'”

Other photos obtained by Starcasm include two young men holding firearms. The photos appear to have been taken inside Mary’s home.

As RHOSLC fans know, Mary may live under the same roof as her son but rarely knows what is happening in his life.

Robert and Alexiana have their “own wing” inside Mary’s mansion, which may be why she was unaware they secretly married in August 2022.

According to records, Robert and Alexiana tied the know on August 18, 2022, in Hollady, Utah, when they were 19 and 18, respectively.

“They both live in my house, but I don’t see ’em much,” Mary revealed on a recent episode of RHOSLC. “We kind of have our own wings.”

“One day, like, they were getting dressed, and he was rushing to go do something,” Mary said in her confessional interview. “He was dressed up nice, and she was dressed up nice. But they were running — like, full-blown running, like, with all their might. But I didn’t know they were going to go get married.”

It’s no secret that Mary’s lack of awareness regarding her son previously caused legal issues for them. Mary and Robert Jr were charged with “contributing to the delinquency of a minor and unlawfully providing shelter to a runway” in April 2021.

These charges are believed to have been connected to Robert Jr’s now wife, who would have been 16 or 17 at the time.

The police officer who removed the young woman, believed to be Alexiana, explained law enforcement’s narrative on the situation in a statement:

I responded to assist. The maid initially answered the door when we attempted contact. I advised the maid to tell the suspect, Mary that we needed to talk to her. I advised that if Mary did not come to the door, we would get a warrant and make entry, and then take her to jail. I stated that if she came to the door, jail could be avoided.

Mary eventually came to the door. I advised her that we now knew the juvenile was in the house. Mary stated she was not but agreed to check her son’s room. She then came back with the juvenile.

I advised Mary that charges could be screened against her son. At this time I had not been informed of the specifics of the evidence against Mary and was not sure if there was enough evidence to charge her or not. Since Mary had voluntarily let us in and brought the juvenile to us I determined that any charges could be screened against both her and her son.

The criminal charges against the RHOSLC star and her son were later dismissed.

“The charges sound sinister, but the reality of the situation is much different,” Robert Cosby Jr’s lawyer, Clayton Simms, told FOX 13 following a court hearing in October 2021. “It’s simply a case where Robert’s girlfriend’s mother didn’t want him hanging out, so she called the police.”

The Real Housewives of Salt Lake City season 4 airs Tuesdays at 9 p.m. ET on Bravo.

I thought he had processing delays and was neurodivergent. Turns out, he was just high as a kite!

He does look like Mary so maybe he does have some of her mental "quirks" other than being high.

That guy is either stoned or mentally challenged, probably a little bit of both. I guess that what happens when you breed wif' you grand ndaddy. I believe the biological term is incestuous conception.

Stoned and in a stupor most likely. Mary's husband is biologically only his father, not grandfather. He is Mary's former step grandfather. Meanwhile he is doped up because his father is never there and his mom is mentally disturbed. They have almost an arranged marriage to run their church (cult?) business. IMO

He is slow as fuck 'not all there for sure, anyone can see that, but how else would he turn out.
Snarky Enigma November 14, 2023 - 3:05 pm
Who knows, who cares ... the important thing is that he never breeds.

He's been spoiled all his life, tough love kick his ass out with the wife find a job. no more money or living off with mama. You can teach them right from wrong but they have a choice when they turn 18. They can be the best parents in the world and their kids can still take the wrong path.

That's really sad...hopefully, she gets him help and he takes it. Explains why he behaves the way he does on camera.

W O W . He is a mess. She had one child, and most probably, due to her strange lifestyle and addiction to brands, she screwed this kid up.

It says a lot that he had to post it on social media to get her attention and the attention of grandpappy.

I think so, too. He wanted attention and structure from his parents but didn't happen because they are both irresponsible and in a bad marriage, IMO. Mary is too messed up to be a good mother. The father doesn't even live in the same state half the time.
675309 November 13, 2023 - 3:11 pm
The father living away from them half the year was a problem, too. Of course Mary is a bad mother. If the crap didn't mess his brain up too much, he can probably be okay. The parents need to get together and focus on getting him straightened out and then they need to divorce. Surely he'd be better off with the father if he'd take responsibility and help him. ?
