Fights & Frenemies! 'Real Housewives Of Beverly Hills' Season 7 Secrets REVEALED

Filming for Real Housewives of Beverly Hills Season 7 is gearing up and, according to a source close to production, it is going to be nastier than ever before! As viewers know, fan favorites Yolanda Hadid and Erika Girardi are NOT returning next season. But while producers scramble to find suitable replacements, RadarOnline.com has exclusively learned that the series vets are already throwing the shade! Click through 7 shocking photos to find out why.

Emotions were on full display at the RHOBH Season 6 reunion between Girardi, 45, Hadid, 52, Kyle Richards, 47, Lisa Vanderpump, 55, and WWHL host, Andy Cohen, 48!

Throughout the span of the show one thing has remained constant – Vanderpump STILL rules! "It has become really clear to Lisa throughout her time on the show who her real friends are and who her enemies are. People really have shown her their true colors," a source close to the network told RadarOnline.com.

Kathryn Edwards joined the cast for Season 6, but the source told RadarOnline.com, "Kathryn really didn't bring anything interesting to the table and she is going to have to start a lot more drama next season to stay on beyond this."

As RadarOnline.com reported, there was serious bad blood last season between Hadid and the veteran housewives, Vanderpump and the Richards sisters. However, the source told RadarOnline.com that "they have all decided to just let it go. They do not want any of the drama from last season to carry over into this season."

"The last couple of seasons have been very dramatic for a lot of the ladies," said the source, adding, "The one common thing in the new season between all of them is that they really do want to become better women."
