Mary Cosby allegedly called Lisa Barlow’s 12-year-old son, Henry, the R-word in a heated argument amid production for “The Real Housewives of Salt Lake City” Season 5, multiple sources exclusively claim to Page Six.
One insider claims that the offensive remark was made during a “crazy fight” that took place between the women earlier this month, noting that Barlow’s castmates — including returning stars Heather Gay, Whitney Rose, Meredith Marks and Angie Katsanevas — were perturbed by Cosby’s part in the exchange.
“The entire cast … was beyond grossed out” by Cosby’s alleged use of the slur, the source explains.
A separate insider emphasizes that the Vida Tequila businesswoman, 49 — who shares Henry, affectionately nicknamed “Baby Gorgeous,” and his older sibling, Jack, 19, with husband John Barlow — was “very upset” with Cosby, 51, for the alleged affront on her son.

However, a third source tells Page Six that Lisa and Cosby have since put the dispute behind them, pointing out that both ladies are currently filming for a cast trip in Puerto Vallarta, Mexico.
“They made amends over the situation and are moving on,” the insider shares.
It’s unclear what prompted Cosby’s alleged verbal attack on Lisa’s youngest child, or if the incident will make it to air when “RHOSLC” returns to Bravo.
Page Six has reached out to reps for Lisa, Cosby and Bravo for comment.
Cosby has a history of saying off-color comments on camera.
She notably called series alum and convicted fraudster Jen Shah a “Mexican thug” during 2021’s “RHOSLC” Season 2 — before the latter was incarcerated for wire fraud and money laundering.
Cosby later apologized to Shah, 50 — who is of Tongan and Hawaiian descent — in a statement shared to her Instagram Story.
“I would like to take this opportunity to address a comment I made on the last episode of ‘RHOSLC.’ I used poor judgment in my choice of words. Please accept my apologies,” Cosby wrote at the time.
“I was not trying to single out the Mexican culture. I am African American and I know racism first hand,” she continued while adding her words were “reckless.”
One month after Cosby referred to Shah as a “Mexican thug,” she came under fire once again for another racially charged jibe.
Cosby was at a luncheon with Season 2 cast member Jennie Nguyen — who is of Vietnamese descent — when she told the one-season “Housewife” she liked her “slanted eyes.”
“What the hell? Did Mary just say she likes my slanted eyes? Does she not know it’s inappropriate?” Nguyen said in one of the episode’s confessionals.
Rather than say sorry, Cosby doubled down on “loving” Nguyen’s eyes, insisting that she “didn’t mean any harm” by her comment — and only meant it as a “compliment.”
Aside from her questionable assertions, the controversial preacher — who is infamously married to her stepgrandfather, Robert Cosby Sr. — has also been accused of running her Faith Temple Pentecostal Church like a “cult.”
Former parishioners detailed some alleged misconduct in a shocking September 2021 Daily Beast exposé.
They alleged that Cosby — who purportedly referred to herself as God — pressured them to empty their bank accounts for the church while living a lavish lifestyle herself, and intimidated members by warning them they’d be “condemned to hell” if they ever left.
Cosby, for her part, has denied such claims.
“Clearly I’m not gonna get on national television, be a ‘Housewife’ and be in a cult,” she told “Entertainment Tonight” in January 2022.
“Like, come on. I believe in my church. There’s no cult. My church members, they know those are false allegations. Those are ridiculous. It’s the people that are looking for fault.”
Cosby was part of the original “RHOSLC” cast when it premiered in 2020, maintaining her full-time status through Season 2.
After skipping that year’s reunion, she didn’t participate in Season 3 but rejoined the franchise as a “friend of” the cast for Season 4.
The capacity in which she has filmed for Season 5 has not yet been announced.
“The Real Housewives of Salt Lake City” is available to stream on Peacock.
