It’s Lisa Rinna vs. Kim Richards… round two? Three? Who knows.

The Real Housewives of Beverly Hills
stars go head-to-head again on Tuesday night’s all-new episode. In the preview, the ladies confront each other at Kim’s sister, Kyle Richard’s, game night.

“I never said anything about your husband, [Harry Hamlin],” Kim starts, and immediately there’s an issue. Kim did kind of say something about the actor back in season five, when she suggested there was a secret Lisa was hiding about Harry while the cast was in Amsterdam.

“Yes, you did,” Lisa responds. “How dare you! Are you kidding me?”

Kim later confessed that she didn’t really have any dirt on Harry, and just made the suggestion to fight back against Lisa, who was questioning her sobriety at the time. That topic seemingly comes up again on Tuesday’s episode.

“Let’s talk about your arrest,” Lisa fires back, referencing Kim’s 2015 shoplifting case.

“I really didn't expect it to go down the road it went,” Kim told ET in December at the show’s premiere party in Beverly Hills. “I wasn't expecting the drama again, the way it did. But you know, it's the Kim and Lisa [dynamic]. What can I say? It happens.”

“Well, what can you expect from me?” Lisa said at the time. “I will bring it, always.”

“Kim and Lisa Rinna, I don't think, will ever be the same after Amsterdam,” Kyle offered. “They tried to do the right thing, and be civil and all that, but it just doesn't seem to go well... ever. And I think at some point, you kinda got to say we're just never going to get along and see you later.”

The ladies’ drama will seemingly expand this season to include new cast “friend,” Eden Sassoon. At least, according to returning co-star Camille Grammer.

“I have a storyline that weaves in a bit with Kim, and Eden and Lisa Rinna, so we'll see,” she said. “There's a lot going on inside of [Eden]. She's a recovering alcoholic and so is Kim, so there's an interesting weave of a storyline there. So, we'll see.”

Viewers met Eden on last week’s episode, when Lisa and Erika Girardi visited her Pilates studio. While Eden was credited as “Lisa’s friend,” Lisa admitted that’s not the case.

“It looks like I bring Eden into the group, but I actually don't,” Lisa confessed. “I just happen to live very close to where her Pilates studio is, so let's be at least honest, shall we? We will always be honest. I get to know Eden. I knew who she was, and of course, I always was in awe of her father, [Vidal Sassoon]. I meet her on the show, I do not bring her on the show.”

Still, that doesn’t mean a friendship isn’t formed.

“I've never had an enemy in my entire life,” Eden told ET, but added that her “sassy” personality might not gel with all the women.

The Real Housewives of Beverly Hills
airs Tuesday nights at 9 p.m. ET on Bravo. For more scoop on the new season courtesy of Erika, watch the video below.
