Things are still pretty bad between The Real Housewives of Beverly Hills star, Kyle Richards and her older sister, Kathy Hilton.
It's gotten to the point where their fractured relationship has affected other family members.
Nicky Hilton, who married James Rothschild in London this past July, is reportedly pregnant with the couple's first child.
Richards, upon hearing the news, "immediately" picked up the phone to congratulate her niece.
Hilton is "angered that her society wedding was included as a storyline on the Real Housewives of Beverly Hills," the source added.
"The wedding was everything Nicky wanted it to be, but feels it has been tainted by Kyle letting the entire world about all of the drama that went on behind the scenes."
One of the reasons for the tension between Kathy and Kyle's families is that the latter's husband, Mauricio Umansky, left Rick Hilton's real estate agency to start his own.
Umansky and two of his daughters were not invited to Nicky's wedding.
"Nicky didn't feel bad for not inviting Mauricio to the wedding. She feels like Mauricio betrayed her dad, period," the source said.
"Nicky is extremely loyal to her parents, sister, and brothers."
The issues kept piling up from there, and this season, Richards did mention that she is developing a show based on her life as a child star in Hollywood. Richards told Vanderpump on the season premiere that her sisters were not happy about their personal stories being aired.
Despite posing for a photo together at Kris Jenner's 2015 Christmas Eve bash, Kyle and Kathy are still at odds.
"That photo was a total set up," the source told Radar at the time. "They're not getting along at all right now because their family issues go much deeper than they will ever reveal on a reality show."
As for Nicky getting over everything, and extending an olive branch (as well as a baby shower invite) to Richards is out of the question.
"No way, it won't happen," the source added.
"Nicky has completely frozen Kyle out."
