Kyle Richards was reportedly “humiliated” when photos of Mauricio Umansky kissing the much younger Nikita Kahn hit the web last month amid their ongoing separation.

According to a new report, Mauricio, 54, was hoping to get back together with Kyle, 55, until the Real Housewives of Beverly Hills star came across pics of him and Nikita, 33, showing off their relationship in Mykonos, Greece, and promptly removed “wife” from her Instagram bio — and reunited with rumored flame, Morgan Wade, 29, in Minnesota.

“Kyle said she felt humiliated,” a source told Life & Style on August 5. “She believed Mauricio was gallivanting in public with this young chippie to show her what she’s missing — but this was the end of their marriage right there!”

Although Kyle was allegedly done at the sight of Mauricio kissing another woman, a friend of the estranged couple suggested that Mauricio felt it was fair for him to seek companionship since Kyle has shared cuddled-up photos of her and Morgan.

“It’s really grinding Mauricio’s gears, seeing Kyle play this are-they-or-aren’t-they lovers guessing game with Morgan to draw attention to herself,” they noted. “Meanwhile, the fact is that Mauricio had really hoped their marriage would fall back into place, but he figured he was a sucker letting grass grow under his feet while Kyle took her time making up her damned mind!”

“Now, he has forced her hand — and he doesn’t feel bad about it one bit!” the insider added.

As Kyle reportedly grows increasingly annoyed by Mauricio’s new romance with Nikita, a model and actress, she’s been staying busy filming the upcoming season of RHOBH, recently traveling to St. Lucia, where she showed off her fit frame in a bikini selfie that she shared on her Instagram Story.

As RHOBH fans may have seen, Kyle celebrated two years of alcohol-free living last month with a post on her Instagram page in which she admitted that going two weeks without drinking once “seemed impossible.”

“I’m proud of the fact that I’ve had the willpower to stay on this path. I know many people would love for me to start drinking again. Even friends with the best of intentions. Everyone loved ‘Party Kyle,’” Kyle wrote. “I think that was the hardest part of all of this. The resistance from others. The old me , the people pleaser, did struggle with that aspect of it. And I realized right away that I wasn’t going to have a ton of encouragement.”

“But my mental and physical health became a lot more important to me than feeling like I had to be ‘on’ at a party or social setting,” she continued. “I’m not going to lie… the fact that I looked better because I wasn’t drinking was also incentive to not veer from the road I am on. But the real reward is how I feel on the inside.”

The Real Housewives of Beverly Hills season 14 is currently in production and expected to begin airing on Bravo sometime later this year or early next year.
