Kyle Richards spoke about the upcoming season of The Real Housewives of Beverly Hills at a party at PUMP Lounge earlier this week.

While mingling with her co-stars, including Erika Girardi, Lisa Vanderpump and Dorit Kemsley, Kyle discussed changes in the cast and the possible return of her older sister, Kim.

"Each season, someone new seems to come in and shake things up a bit, so we do have a little shift this season and it's interesting," Kyle teased during an interview with E! News this week.

Although Kemsley's addition to the show hasn't been officially confirmed by the network, she has been spotted hanging with the Real Housewives of Beverly Hills cast on multiple occassions and appears to be close with Lisa Vanderpump.

As for what she thinks of the recent cast changes, Kyle said, "Well, it's new. You never know. In the beginning, it's always great, and then later, you're like, 'Oh my god, this is a nightmare!'"

As filming continues on season seven, fans have been wondering of Kyle's sister, Kim, who appeared in a guest role during season six, will return, and according to Kyle, it is a definitely possibility.

"I think she is [returning,]" she said. "I can't confirm that, but I would like to see her back and I know a lot of people would... It gives her purpose and accountability and somewhere to be every day. I feel like it was a good thing for my sister."
