'RHOBH' Tea Time: Bethenny Frankel Crashes Beverly Hills Drama During NYFW
The Cast of 'The Real Housewives of Beverly Hills' Season 8

"I don't lie!" Bethenny tells Lisa Vanderpump. "Not in this house, honey. You're in my town. Don't call me a f-cking liar!"

The air was thick on Tuesday's "Real Housewives of Beverly Hills" after Kyle Richards, Lisa Vanderpump and Dorit Kemsley's explosive fight -- but things got even more heated when "Real Housewives of New York" firecracker Bethenny Frankel found her way into the mix.

The Beverly Hills ladies were all still in New York for Fashion Week, and despite the preceding night's drama, both Vanderpump and Dorit showed up to Kyle's trunk show -- as did Bethenny, Kyle's friend of over 25 years.

While Kyle and Bethenny were talking and catching up, Lisa approached them.

"She said she got caught in the crossfire," Bethenny said to Lisa. "Something happened, and she was defending you, and she got f-cked."

"And I thanked you for defending me," Lisa said to Kyle.

"But you thanked me, but then you were like, 'I'll ride with you, Dorit,'" Kyle replied.

"It was a thank you-f-ck you," Bethenny said. "That's a thuck you, we call it."

"Would you just stop?" Lisa said to Bethenny. "Don't look at me like that. I see that look on your face, and I know what's coming in my direction, so settle down."

Lisa later told Bravo cams, "So now Kyle's got Bethenny as a backup. Well, I have no problem going head to head with Bethenny. I'm a big girl, too, and I'm the bigger person, so there. F-ck you -- thank you, I mean."

Bethenny then jokingly made a comment about how maybe Lisa's more loyal to Dorit because she thought Dorit was also British.

"Dorit's not British," Kyle said.

"Oh, she isn't? What's that accent?" Bethenny replied. Kyle burst into laughter.

"Don't start," Lisa said. "You know exactly what you're doing."

Bethenny, looking genuinely confused, kept saying, "I swear to God, I don't. I swear to God, I don't. I swear on my life. Don't you f-cking tell me what I'm doing! You guys lie. I don't lie. Not in this house, honey. You're in my town. Don't call me a f-cking liar."

"She's from Connecticut!" Kyle interjected. "He's British. She's from Connecticut."

Bethenny then tried to mediate some sort of apology between the two, which of course, didn't go over well at all.

"The Real Housewives of Beverly Hills" airs Tuesdays at 9 p.m. on Bravo.
