Kyle Richards and Kathy Hilton got into the Christma spirit late last week.
With each other.
The former friends, who have seemingly been involved in a major feud, both attended a December 24th party hosted by Kris Jenner last Wednesday night.
"'Twas the night before Christmas ..." Richards captioned a photo of her and Hilton at the event, with the stars joined by good friend Faye Resnick.
Just a week prior to the shindig, an insider told People Magazine that the Real Housewives of Beverly Hills cast member - who isn't getting along these days with sister Kim Richards, either - 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 source explained.
"The animosity has been building up for awhile. Mauricio isn't even welcome in the Hilton house."
Kathy, of course, is the mother of Paris Hilton and Nicky Hilton.
As those who watch The Real Housewives of Beverly Hills online know well, Kyle has also been open about this drama nearly every week on her Bravo hit.
She recently told viewers that she was uninvited to Nicky Hilton's wedding.
"Kathy is mad that Kyle brought Nicky into the fight," People write, adding that neither Richards sibling was invited to the Hiltons' annual Christmas party on December 12.
"There is so much drama in that family. It's sad that even over the holidays, they still can't get along."
