Erika & Lisa Vanderpump Feud On 'Real Housewives Of Beverly Hills,' Thanks To Kathryn's Pot-Stirring

The Real Housewives Of Beverly Hills is a master class in how to start drama and betray your friends. If you ever thought you needed to know how to pit people against each other, sit down and take notes, because they have really got it down to an absolute science. Tuesday night's episode displayed a prime example of these shady shenanigans when Lisa Vanderpump and Erika faced off on RHOBH during Yolanda's dinner party, and things got pretty heated.

The crazy part was how it all began. Kathryn truly is a professional when it comes to the old drop a grenade and walk away method of starting drama. This time, she managed to wind up the queen herself, Lisa Vanderpump. I do have to say that it was pretty impressive to watch how nonchalant Kathryn was about the whole thing once it started exploding around her. But eventually, it all came back to her, which clearly caught her a bit by surprise. She ended up getting caught in the crossfire, because these Housewives don't tend to keep the sources of their gossip private. If you say it, you better own it in Beverly Hills.

During dinner at casa de Vanderpump, Kathryn decided to spill to Lisa that Erika had warned her not to get caught in the Vanderpump "web." She basically told Lisa that Erika thought she was manipulative, and Lisa was rightfully miffed, to put it lightly — the look on her face could have frozen the sun. Of course, Kathryn might as well have stroked a white cat and laughed menacingly as this happened.

Luckily for us, there was a dinner party the following evening, because we needed to see Lisa eviscerate someone. Naturally, she confronted Erika immediately at dinner and I never thought I would see the day, but Erika looked slightly intimidated. To her credit, she came clean and admitted what she had said about Lisa, though the whole confrontation got really intense and ended on a sour note, with Lisa giving that sun-melting glare to the back of Erika's head.

You didn't think Kathryn was going to get out of this shrapnel free, did you? No way. After her meeting with Lisa, Erika made her way right to Kathryn and asked her why she ratted her out. Kathryn basically said that she tells everyone everything that is said to her, and they all should accept that. Because why not?

These ladies can really get the pot stirring in a big way. It will be interesting to see if Lisa, Jayne, and Kathryn continue the war of sass this season on RHOBH... and if Lisa manages to kill someone with a glare alone.
