Gina Kirschenheiter Wonders 'Who the F--k' Meghan King Edmonds Is in RHOC Exclusive Sneak Peek

Things heat up between Gina Kirschenheiter and Emily Simpson on Tuesday's episode of "The Real Housewives of Orange County," and a former castmember gets caught in the crossfire.

In TooFab's exclusive sneak peek of the group's birthday trip to celebrate Shannon Beador, Emily refuses to come out of the bathroom because she's hysterical over her feud with Gina. Last week, Gina learned the man Emily tried to set her up with -- Shane's cousin -- had a girlfriend, and he told Gina that the Simpsons both knew.

In the bathroom trying to console a blubbering Emily was "RHOC" alum Meghan King Edmonds, who was at the receiving end of Gina's initial fury when she reluctantly got up from the table and decided to go check on her friend. By the way, a confrontation in any bathroom is the self-proclaimed germaphobe's "worst nightmare."

"I tried to do something nice; it didn't work out. No harm, no foul. You didn't go out on a date. It's not like you were emotionally invested in him and then you found out," Emily was seen explaining to Meghan when Gina came charging through the door. "Hello?!"

Gina was livid. "I'm just gonna tell you this: I've done my best. I just met Meghan. I would never bring her into my business," she said, looking directly at a wide-eyed Meghan. "You shouldn't get involved in any of our business! And you know what I told everybody else at that table? 'I'm gonna talk to her about it.'"

"Who the f--k is Meghan?!" Gina animatedly shouted during a later confessional. "I just met this girl, and you're gonna spill your guts to her in the bathroom?!"

After some back and forth, Edmonds snuck into one of the stalls, leaving Kirschenheiter and Simpson to duke it out on their own.

"I think what I think, and that's it! Have more confidence about shit!" Gina hurled at Emily, who barked back, "How can I when I f--king call you three days in a row, and you won't even call me back?!"

"Whatever, Emily! I'm pissed at you!" Gina shouted, as Emily got up in her face and yelled back, "I don't give a f--k! I'm pissed at you! I am pissed at you!"

Emily was inconsolable. She stormed out of the bathroom and demanded that an off-camera producer get her "a f--king car." The producer calmly urged Emily to "hang tight for just one sec," but she couldn't believe she was "even dealing with this bullshit!"

Back in the bathroom, Gina was still going. "I can only be a friend to her as much as I can be a friend to her," she said to a still-wide-eyed Meghan. "I'm allowed to be upset at my friends, and it doesn't mean that all of a sudden that I've abandoned you! Like, she has abandonment issues!"

"The Real Housewives of Orange County" airs Tuesdays at 9 p.m. on Bravo.
