I'm pretty sure. I'm hopeful." "We all are hopeful," added Crystal Kung Minkoff, 36, Beverly Hills' newest Housewife.

The Bravo series has previously delved inside Hilton's relationship with both her sisters, including former RHOBH star Kim Richards. Michael Tran/FilmMagic. Hilton told PEOPLE in June that the show has brought her closer to Kyle after years of estrangement. "I never would have thought I'd say yes to this," she said.

Kyle Richards: 'It Feels So Good' After 11 seasons, Richards was the reason Hilton decided to join the cast. "Kyle convinced me to do it. And I was flattered," she said. "I thought it would be an opportunity for us to spend time together. I really missed her." Amy Sussman/Getty In an August episode of RHOBH, Richards shared how she drifted from her oldest sister after their mother died of breast cancer in 2002. "When my mom passed away, the dynamic between Kathy, Kim and I changed because my mom was always the mediator," Kyle explained. "If my mom was still alive, we would've still had the arguments that we had, 1,000%," she said. "But all the years of not spending time together, my mom would never have tolerated that and she would have brought us all together, always."
