Bethenny Frankel Rips 'RHONY' Co-Star Tinsley Mortimer: 'F--k That B--ch' (Video)

"F--k that bitch," Frankel said of "Real Housewives of New York" co-star Mortimer on "Watch What Happens Live" on Wednesday.

"Here's what it is: This is my real life, this is a reality show, and I meet someone at a party and I say 'Hi, nice to meet you.' I don't go down on them."

"Everybody has this preconceived notion that they come on a show that's been on for 10 years, they're gonna come in and, 'Oooh, I'm gonna make Bethenny hate me or like me or I'm gonna fight with her,'" she continued. "It's like, 'Hey, hi, how are you?' That's it. Basic. Nothing. We don't know each other."

When a fan asked Bethenny how she would've handled herself during the "RHOA" reunion if she were Kandi Burruss, she said she didn't know how Kandi "contained herself."

"I would've needed to hire Phaedra as a lawyer to represent me in whoopin' her ass," Bethenny said. "I would've beat her ass. That was insane. She's a lawyer, and she tried to ruin someone's brand and career and she has a kid? I mean, it was despicable."

In a game of "How Much You Wanna Bethenny?" host Andy Cohen put Bethenny's knowledge of fellow guests Kyle Richards ("RHOBH"), Erika Jayne ("RHOBH") and Eric Stonestreet ("Modern Family") to the test. Bethenny was given five random facts and asked to identify to whom they pertained. She got four out of five facts correct.
