Kathy Hilton Says She’s 'Already Filmed a Few Times' with New RHOBH Cast Member Rachel Zoe

Kathy Hilton is loving having Rachel Zoe on The Real Housewives of Beverly Hills.

While chatting about her new Summer 2025 jewelry collection with Anna Zuckerman, which launches June 16, Hilton, 66, told PEOPLE she and Zoe, 53, have "already filmed a few times together, and she's fabulous."

"She's family," Hilton says. "It's going to be great. She's a great addition."

Zoe confirmed she was joining the RHOBH season 15 cast on June 6.

In a Instagram video, Zoe said: "It's been a while and you've been asking me to come back to television, and I said when the stars align or it makes sense or I have enough to say to share with all of you, and now is the time. Really excited to be with all of you again and I hope you are too, so let's have some fun! Mwah!"

Zoe first rose to fame on another Bravo show, The Rachel Zoe Project, which aired from 2008 to 2013 and chronicled her life as a celebrity stylist and designer.

Since the show's conclusion, Zoe has remained active in the fashion and lifestyle space, in part through her newsletter The Zoe Report, which launched in 2009.

Zoe and Berman revealed their separation in a joint statement, saying, "After 33 years together and 26 years married, Rodger and I have come to the mutual decision to end our marriage. We are incredibly proud of the loving family we have created and our countless memories together."

"It's unfortunate what happened," Hilton tells PEOPLE of Zoe's separation. "I never like to see that happen, but she seems to be doing strong. She's strong and doing well."

News of Zoe's casting came after Garcelle Beauvais' exit from the series in March following the conclusion of season 14. At the time, Beauvais, who had been on the show for five seasons, said she was leaving so she could devote time to her sons and focus on new projects.
