Kathy and Rick are not the only family members that have their say in this drama. Kyle’s wife, Mauricio Umansky’s wife is Rick’s sister. Kyle’s wife’s husband is also Rick’s sister. The two families have been interacting with each other in an attempt to start the feuding down the road.
The drama between Kathy Hilton and Kyle Richards consistently stems from some sort of family disagreement, and this particular instance is no exception. Kyle’s husband Mauricio Umansky once made a professional decision that deeply triggered Kathy and her husband Rick Hilton. In his memoir “The Dealmaker” (via Page Six), Umansky wrote extensively about leaving his brother-in-law’s real estate firm, Hilton & Hyland, to start his own company, The Agency in 2011. After Rick was unwilling to make Umansky a full partner, the real estate broker wasn’t interested in staying on. Umansky wrote, “He and Kathy held tremendous anger toward us, which is not the way I choose to live my life. Naturally, Kyle was very hurt by their reaction, and it was a difficult pill for her to swallow.”
So, why were Kathy and Rick so upset by Umansky’s decision? Umansky speculates that they were worried that he would scoop up Rick’s clients. He noted that they stopped talking to him and Kyle and no longer extended invitations to holiday festivities.
Umansky isn’t the only family member looped into Kyle and Kathy’s feud. When Season 1 of “RHOBH” aired in 2010, Kyle’s behavior toward their sister Kim Richards was a big problem for Kathy. In a 2021 appearance on “Lunch with Bruce” (via Us Weekly), Kathy shared, “I didn’t watch [‘RHOBH’] because I was so hurt at what happened that first season and I didn’t speak to my sister for a long time.”
