The hit reality show, which is based in Los Angeles, will be back in the new year, one of the show's producers has confirmed. It has not been revealed which housewives will be returning for the next season.
Kathy accused the two women of being 'bullies' who would 'throw anybody under the bus'.
Speaking about the break, executive producer Andy Cohen said: "Beverly Hills, we're taking a minute break."DON'T MISS:

"And then we'll be back shooting with them in the new year," he added in an interview with E! News.
Elsewhere in his interview, Andy shared plans for the other branches within the franchise. He said: "We are shooting the new Real Housewives of New York City that I'm excited about, and then we'll get Legacy going."
As well as Kathy, Lisa and Erika, the latest season also featured Kyle Richards, Crystal Kung Minkoff, Dorit Kemsley, Garcelle Beauvais and Sutton Stracke.
Speaking about the ultimatum she made to Bravo, Kathy said she was made to feel intimidated by some of the other women.
"I had said I would only be willing to come back if the cast [changed].
"If it was completely the same, absolutely not because I feel they are two bullies that intimidate a lot of the other girls," she said in an interview with TMZ.
There was even more drama at the RHOBH season 12 reunion, which led to a huge argument between the housewives.
Kathy, the mother of Paris Hilton, branded Lisa the "biggest bully in Hollywood" in the action-packed show.
"You are the biggest bully in Hollywood and everyone knows it," she said after Lisa compared Kathy to "the devil" earlier in the series.
Kathy also suggested Lisa has attacked her character in order to 'save her job' on the Real Housewives of Beverly Hills.
Addressing Lisa, Kathy said: "Maybe you wanted it on camera because your contract was coming up."
