Lisa Barlow's relationships with Whitney Rose and Thurston CarteAngie Katsanevas have turned icier than a Utah winter.

In fact, Lisa slams her Real Housewives of Salt Lake City costars for bad-mouthing her behind her back in E! News' exclusive sneak peek at the Bravo series' Oct. 9 episode.

"You and Angie talked to Meredith [Marks] about me, and that is also gossip," the Vida Tequila founder yells at Whitney in the preview. "I've worked really hard on this friendship with Meredith. I don't need you guys going to her and saying, 'Do you trust her? Do you think she's your friend?'"

But when Whitney says she feels "steamrolled" by Lisa's heated confrontation during the group dinner, Lisa unleashes more venom.

"I love that this is your keyword," she shoots back. "You two, steamrolled. You feel steamrolled when I come to you with facts. Is that what you feel steamrolled by?"

Angie then accuses Lisa of being angry that she and Whitney have gotten closer. Lisa's response?

"We went to lunch and I told you I don't care if you back Whitney, I know you back Whitney," she retorts. "What got me upset is you meddling in my friendship with Meredith."

Angie doubles down in claiming her friendship with Whitney is the root of their issues, prompting Lisa to explode with, "I don't care! I don't give a f--k! I say what I mean. I care that you went to her with stuff I said to you in confidence and I said, 'You just changed our relationship.'"

And when Angie claims, "You don't like that I'm not just doing everything you want me to do," all hell breaks loose.

"I don't give a f--k what you do!" Lisa screams. "Don't do that to me, you f--king b--ch!"

But Angie has a response just as fiery.

"You've been a f--king b--ch to me at times," she yells at Lisa. "You've kept me up at night. You treat me like s--t."

See the drama play out when The Real Housewives of Salt Lake City airs Wednesday at 9 p.m. on Bravo. And don't miss out on picking up a pint of Van Leeuwen's new limited-edition ice cream flavor, The SLC Scoop, available nationwide starting Nov. 19.
