EXCLUSIVE: Erika Girardi's Lack of Underwear Sparks Unexpected Drama With 'RHOBH' Co-Star Dorit Kemsley

Who knew drama could start over panty lines? Or rather, lack thereof.
ET has your exclusive first look at the next all-new episode of the The Real Housewives of Beverly Hills, which features newbie Dorit Kemsley struggling to wrap her head around Erika Girardi/Jayne as a person. (Remember, she’s two people -- but not two-faced.)

“I had lunch my husband the other day, and I had mentioned, you know, ‘Erika’s this beautiful girl, she’s very, very poised,’” Dorit tells Erika. “It’s almost like you’ve got this aura about you, very, very strong. A bit guarded.”
“I think in life, you know, when you meet people -- and you meet people for the first time -- it’s best to be cautious,” Erika says.
“Because you’re cynical or… what is it?” Dorit’s husband, PK, asks.
“I mean, I am what I am,” Erika says.
“I don’t trust everybody,” she adds in a confessional. “Friendship is earned. Respect is earned. It’s not just given. Sorry. Well, not really.”

The conversation then shifts to underwear, as Lisa Vanderpump asks Erika if she could loan Kyle Richards (who seemingly isn’t wearing any) a pair.
“I don’t have any,” Erika announces. “That’s right. Don’t put your hands up my skirt unless you wanna see what’s up there.”
“I have on a Mugler dress,” she explains. “Why would I break up a beautiful design with an underwear line, with a panty line? Really?”
The underwear moment leaves Dorit and PK confused.
“Erika, you’re the most out-there person, though,” PK says.
“It’s a stage persona,” Erika snaps back. “I’m a real, like, introvert.”

Erika says, because of her over-the-top, in-your-face stage persona, Erika Jayne, people don’t expect her to be an introvert -- but she insists she’s incredibly shy.
“I’m just not buying it,” Dorit scoffs in an interview. “Snooty? A bit. Cold, frigid? Yes. Introverted? No.”
ET recently sat down with Erika, and she had this to say: “Some people call me cold, I just happen to think I can spot B.S. right away.”
