Kathy Hilton Back on 'RHOBH' ... After Producers Pay Up

Kathy had previously refused to film anything for the franchise's new season because she felt she was being undervalued by show producers. It took several weeks, but both sides were able to come to an agreement that will see Kathy as a friend of the cast, making regular appearances on the show.

We spoke with Kathy's sister, and full-time cast member Kyle Richards last month about KH's absence as the rest of the women were seen shooting across town. Kyle told us Kathy had just been busy planning her daughter, Paris Hilton's wedding -- but our sources say the real hang-up was money.

Kathy is expected to begin filming with the Bev Hills cast just after the holidays. As we reported, production had been suspended late last week when 3 members -- Lisa Rinna, Erika Jayne and Garcelle -- tested positive for COVID-19. Fortunately, we're told all women were vaccinated and have had mild symptoms.

As for everyone else who tested negative -- we're told production will resume at some point this week.
