RHOBH's Kyle Richards leaves Mauricio furious after revealing his secret amid marriage troubles

Kyle Richards spilled a secret which made her husband Mauricio Umansky furious amid their marriage troubles.

The Real Housewives of Beverly Hills star, 54, shared something no one else knew about her husband during a get-together to celebrate their daughter Portia’s 15th birthday.

Of course, the moment was captured on camera and aired during the long-running reality show’s current season on 1 November.

Amidst the celebrations for Portia, Kyle whispered to her husband: “Do your parents know I have a tattoo and you have one too?”

To which Mauricio simply replied: “No.”

However, the tattoo situation didn’t end there.

In fact, it was only the beginning, as she later confessed all to her mother-in-law, Estella Sneider, about her body ink.

And for those wondering why tattoos are such a touchy subject for Kyle and her family, Mauricio is Jewish and tattoos are traditionally banned in the religion.

“I got tattoos,” Kyle told Estella, however, her mother-in-law later confirmed that she had no issue with Kyle’s body art, although she did ask about the significance of the inking.

“Didn’t you do a tattoo for Mauricio?” she asked.

Kyle replied: “Did I put his name? No. That’s a jinx anyway - do you know your son has one?”

And real estate mogul Mauricio, 53, was not happy about his wife revealing his secret.

"What is wrong with you?!" Mauricio said before Kyle tried to assure him that his mum didn't care about the tattoos.

Kyle later shared her regret about sharing her husband’s secret with his mum.

In a confessional, she said: “Why did I open my mouth? I thought, 'Oh, OK, it will be funny in the moment. Wait to see her reaction.' But now, his reaction, I really wish I had not said anything."

Estella also asked Kyle about rumours she heard suggesting that she was about to split from her husband after 27 years of marriage.

"Everything is OK with you and Mauricio, right?" Estella privately asked her daughter-in-law.

“Every time I open Google it was something about you guys separating, divorcing. It got to a point in which I called Mauricio, I sent him a text. I said, 'Is everything OK?'

"Generally I don't believe these things, but it's too much. Who started this?"

You can see the drama play out on The Real Housewives of Beverly Hills which airs Wednesdays at 8 p.m. on Bravo. UK fans can watch the action unfold on Hayu.
