'RHONY' Bad Apple of the Week: Bethenny and Carole's Friendship Dissolves Over Dinner While Luann and Dorinda Debate Drinking Problems

The tension between Bethenny Frankel and Carole has been on the rise for weeks, and the latter finally decided to address her once-BFF during a group dinner in Colombia.

Carole told Bethenny she felt she was being pushed away and asked what her issue with her really was. Bethenny said she thought their friendship had "eroded" and that it started over the summer when Carole was busy training for her marathon and Bethenny was busy with Puerto Rico relief.

Carole pointed out she thought they had both "hugged it out" and moved on, but clearly, Bethenny had not. Bethenny then made a comment about how she didn't want their conversation to be a group affair and reprimanded Tinsley Mortimer for looking their way. Tinsley pointed out -- sassily -- that they were all at the same table.

Elsewhere, Dorinda Medley was sipping on what seemed like her second or third margarita. Luann de Lesseps, who was still sober at the time, said, "Ohhh, it's startin'!" in reference to Dorinda's drinking, and Dorinda fired back, "No, I'm not starting. Don't say that. You should start."

Luann insisted Dorinda starts "turning" and becoming "aggressive" when she drinks, but Dorinda -- seemingly already tipsy -- was not having it. She ordered Lu to apologize, and then proved Luann to be right by getting super aggressive.

"You're gonna start being some uppity thing," Dorinda said. "An ex-Countess got married and doesn't have her countess-ship anymore? Don't you dare talk like that. Why don't you drink some wine and get arrested, honey? And get a felony. You got four."

"I supported you for everything!" Dorinda said to Luann.

Over on the other end of the table, Bethenny and Carole were still going at it.

"I don't wanna do this. I don't wanna do this," Bethenny said repeatedly, putting her hands over her face. "You changed. And last night, I'm hysterically crying, and you walk out. And today, you say, 'She's talking. I don't wanna deal with this.'"

Carole insisted she had no idea Bethenny was crying while Luann reprimanded Dorinda for breaking her glass in front of her.

"I didn't get a mug shot over it," Dorinda fired back.

Bethenny told Carole she didn't "recognize" her. "I don't think you really like me," she said.

Meanwhile, when Dorinda tried to order another drink, Ramona Singer tried to stop her. That didn't go over well. Luann then stormed off, and Dorinda told Ramona she'd "never speak to [Lu] again." Dorinda then went off on Ramona, telling her she "ain't her mother and ain't her daughter." Ooooof.

Back over at the Bethenny-Carole end of the table, the two went down memory lane and revisited every single disagreement they've had so far this season -- and they disagreed on every single disagreement. It was quite the dinner.

On the ride home, Dorinda was drunkenly talking to whoever would listen about her altercation with Luann. "She'll be drinking in three months. She already told me that," Dorinda said.

Back at the house, Luann vented to Bethenny about what went down with Dorinda and began to cry. "I know she was drunk, but the truth comes out," Lu said. Bethenny then told Luann about Dorinda's drunken outburst on their trip to Puerto Rico.

Dorinda, whose lipstick was all over her face, drunkenly cried to Carole about what went down. She later told Bravo cams she felt it would be best for Lu to tend to her own garden and leave hers alone.
