Even though siblings often have their fair share of fights, it looks like Kathy Hilton and Kyle Richards from The Real Housewives of Beverly Hills are still not on speaking terms. It was questioned if it was the right move to bring the mother of Paris Hilton onto the show knowing the sister's past drama. While there's hope they might rekindle their friendship, the move turned out to be detrimental.

The family feud between the Hiltons and the Richards has been going on for over a decade. The standoff started between the spouses, Mauricio Umanksy and Richard Hilton, back in 2010. It was the same year that the franchise premiered, and even though Mauricio had worked for Richard's real estate firm, the hotel king refused to make Kyle's husband a partner. The falling out led to Mauricio choosing to miss out on Nicky Hilton's wedding in London, and Kyle and The Real Housewives of Beverly Hills' Kathy Hilton have never recovered.

Kathy & Kyle Can't Seem To Get Along

According to Page Six, Kathy and Kyle are a long ways from making up, especially after a hostile RHOBH season 12. The 54-year-old revealed that she and her older sister are not currently speaking, noting time has not healed all wounds. Kyle told the outlet that she hadn't seen Kathy "in a while." Sadly their sibling relationship only worsened after the RHOBH reunion, where Kyle was put in the middle of an argument with Lisa Rinna. While Kyle admitted the scenario is very "upsetting," the mother of four hopes the new season won't be too awkward to film.

Is Kathy Jealous Of Kyle?

Feuding sisters Kathy and Kyle are wealthy women as both are said to be worth a few hundred million, but sometimes it is hard not to think that the mother of three was jealous of her little sister. Kyle and Mauricio were very much an underdog story, especially after Richard refused to help his brother-in-law out. However, the Umansky-Richards family did very well for themselves; Mauricio now owns his own real estate firm, The Agency, Kyle is acting once again, and their children are all successful in their own right. It seems Kathy and Kyle's issues are one big case of sibling rivalry.

The much-anticipated The Real Housewives of Beverly Hills season 13 has yet to film, with Kyle even admitting she had to take a step back from the ladies. The RHOBH season 12 reunion took a toll on Kyle emotionally, and even Bravo agreed the cast needed a break. While it would be nice to see Kathy and Kyle make up, they have a lot of healing to do privately before they can move on.
