Kyle Richards “Heartbroken” Seeing Mauricio Umansky Kissing Model Klaudia K

Kyle Richards was “particularly heartbroken” when she saw the photos of estranged husband Mauricio Umansky kissing model Klaudia K.

Mau and the younger model (literally):

An insider told Page Six the Real Housewives of Beverly Hills star was “hurt when she saw Mauricio kissing another woman for more reasons than one.”

The 54-year-old real estate mogul was spotted kissing the 33-year-old model following a sushi dinner date in Aspen. The father of three’s daughters’ age ranges from 16-28.

Mauricio and the blond beauty were caught canoodling as they left Matsuhisa together. “Seeing Mau kiss that woman in Aspen — where he and Kyle have so many memories together as a couple — is especially hurtful.”

The insider elaborated, “Kyle and Mau have a family home in Aspen. They’ve traveled there countless times with their children, so it’s a place that has a lot of meaning for her.”

The new normal:

This isn’t “The first time Mauricio was been photographed kissing another woman. But, this is the first holiday season they’re spending apart since he got his own place.”

“It’s been challenging to see that and it’s just a lot to process.”

“Kyle and Mau are navigating this whole situation better than most, but that doesn’t mean it’s been a cake walk.”

“It’s just a difficult time for Kyle and she’s still processing all of these emotions.”

What about the other model Mau dated recently?

Ukrainian beauty Nikita Kahn started dating Mauricio over the summer and went on romantic trips with him to Mexico. Page Six confirmed that she and the real estate mogul called it quits “just last week.”

Nikita, 33, told Page Six she dumped Mau because they were on different pages. “I wanted a committed, serious relationship, but he’s not ready for that right now.”

“I left because I know what I want and deserve. I’ve accepted that we’re on different paths now. I wish him the best, and I’m focused on moving forward and staying true to what I want in life.”
