Kyle also felt Ken Todd only "escalated" the situation, making it all "very intimidating."
According to Kyle, it was also the last time Lisa communicated with the rest of the cast.
"Unfortunately, our friendship ended on that day," Kyle told People about the fight that took place eight months ago in Lisa's kitchen. "It seems so silly because it did not have to get to this point."
Kyle went on to say the explosive argument "was really upsetting."
"[Lisa] had such an overly dramatic reaction, screaming at me like that," she said. "She can be challenging and stubborn." Kyle also felt Ken Todd only "escalated" the situation, making it all "very intimidating."
Regarding her decision to confront Lisa on that fateful day, Kyle said she felt stuck between a rock and a hard place, noting that if she hadn't told LVP what the other ladies were saying about her, Lisa would've been just as upset.
"I wanted to be honest," Kyle maintained. "We talked about it on camera. So if I had waited until it aired, she would have been like, 'Why didn't you say something to me?' I was the messenger, so I got the brunt of it."
Though Lisa's still on the show, Kyle says she's "cut off all communication with everyone." But that doesn't mean Kyle's closed the door to a possible reconciliation with her friend of over a decade.
"I would like to think we can be friends again," she said. "I always have room in my heart for someone that I have cared about."
But for now, Kyle wants to focus on being "the best mom and wife and work as hard as I can."
"It's a lot to keep in the air, so the time that I do have has to be with people who lift me up," she said. "I want to spend time with people who make me feel good."
The friendship-ending argument all started when Dorit Kemsley saw a Radar Online article she felt LVP planted to make her look bad for having given her Vanderpump Dogs-adopted pup to someone who then took the dog to a different shelter. Dorit brought it up to Teddi Mellencamp, Erika Girardi and Lisa Rinna, who all felt similarly.
They cornered Kyle and asked if she's ever known Lisa to leak stories to the press. Kyle was palpably uncomfortable. After lunch, she went over to Villa Rosa to talk to Lisa about what the women were saying.
"If you read the article, it sounds like it comes from your camp," Kyle said, noting that she had gone to lunch with the girls and that the Radar Online story came up.
Lisa denied the claims made by her fellow castmates.
The conversation got more and more heated until Ken entered the fray. Kyle kept saying she was simply there to deliver the general consensus of the girls, but Lisa and Ken were beside themselves.
"You came here to tell me I am a liar, and I don't appreciate that," LVP shouted at Kyle. "You know what? We're done."
As Kyle made her way out of Villa Rosa, Lisa and Ken stormed upstairs.
"Get the f--k out of my house! I swear to you, I'm done with it!" Lisa shouted. "They're lying bitches. They can go f--k themselves -- all of them! For Kyle to say that to me? I'm DONE WITH IT!"
