The Real Housewives of Beverly Hills season 7 will have some changes that haven't been done before. Details are scarce over what that means, but one of the cast members divulged this small tidbit recently when asked how filming for the show is panning out.

Nastiest season ever?

RadarOnline published a report on Monday with a headline claiming that season 7 of RHOBH will be one of the nastiest ones ever.

It didn't reveal too much other than to highlight Lisa Vanderpump has never known who to trust, Lisa Rinna won't have Yolanda Hadid to fight with, and that all of the women want to find a common ground.

Kyle Richards shares that a "shift" will take place with the case.

She and Lisa Vanderpump spoke with E! News to spill a few hints about what's on the horizon when the new season gets underway.

Kyle was careful in how she revealed what's ahead, but said there's "a little shift this season, and it's interesting." She offered very little on that comment other than to say it's too early to tell if it's a good thing.

She also said Kim might be returning to the show. Despite some fans insisting Kim is better off focusing on her sobriety and not the show, Kyle thinks The Real Housewives of Beverly Hills provides her sister with a "purpose and accountability."

Casting still in progress

As a previous report noted on the cast of RHOBH ladies, Camille Grammer might return but doesn't want anyone assuming it's a "comeback." Dorit Kemsley, a friend of Lisa Vanderpump's who's a fashion designer and married to British property developer, Paul Kemsley, will be on of the new cast members.

Cast members not returning for season 7 are Yolanda Hadid, Kathryn Edwards, and Erika Girardi. Bravo is in the process of finding at least one or two more additions before announcing the official cast lineup.

Lisa Vanderpump didn't have much to add other than to say that things are "OK, but there were wounds to heal."

It was rumored for a few weeks that Vanderpump might not renew her contract with Bravo for season 7, but that she wanted to bring attention to causes she cares about for the LGBTQ community and the cruel slaughter of dogs in China.

The Real Housewives of Beverly Hills season 7 will premiere in either late November or early December 2016.
