Kyle Richards Dishes on the Drama-Filled Season 6 of The Real Housewives of Beverly Hills

Just a week before the party, a source revealed to PEOPLE that the Real Housewives of Beverly Hills star, who is also currently working through her troubled relationship with sister Kim Richards, was no longer speaking to Hilton.

“Kathy’s husband Rick is still mad at Mauricio [Umansky, Kyle’s husband], for leaving [Rick’s real estate company] Hilton & Hyland and starting [successful competitor] The Agency. The animosity has been building up for awhile. Mauricio isn’t even welcome in the Hilton house,” the insider told PEOPLE.

The source also said Kathy, 56, was angry with Kyle for airing their family drama for all to see on RHOBH. Kyle recently revealed on the show that she was at one point uninvited to the wedding of Kathy’s daughter Nicky Hilton.

“Kathy is mad that Kyle brought Nicky into the fight,” the insider said, adding that neither Richards sister was invited to the Hiltons’ annual Christmas party on Dec. 12. “There is so much drama in that family. It’s sad that even over the holidays, they still can’t get along.”
