'RHOC' Preview: Fake Friends & Vodka Shots -- Tamra Barney Flips Off Heather Dubrow, Says She Needs To 'Pull The Stick Out Of Her A**'

The drama is heating up on the Real Housewives of Orange County (with the help of vodka!).

In a preview for Monday's episode on Bravo, new cast member Shannon Beador hosts a dinner party at her home and things with the ladies take a turn for the worse once Tamra Barney gets into the Grey Goose.

"Here's to girls that keep it real," Barney says, clinking glasses full of vodka with Beador.

But after Beador gives Barney an herbal remedy pill that promises to keep you from getting a hangover the morning after, Barney jokes she won't get pregnant to which Heather Dubrow bluntly states, "You can't, you tied your tubes."

Barney flips her the finger and tells Beador, "She can't have fun. Pull the stick out of her ass. Because it's really enlodged sic in her throat."

"Heather's really been getting on my nerves lately," she tells the camera.

"She's been extremely pretentious, she's a know-it-all. She really has this chip on her shoulder that we're all below her. She's up here, we're down here. And I'm just getting sick of it."

Then while the ladies go upstairs to take a tour of Beador's house, Dubrow sticks behind with Barney's husband, Eddie Judge, to stir the pot.

"So we're at dinner the other night, and she's worried that you want a kid," she tells Judge.

"And you have always been very clear, I think, that you don't."

"Right," he agrees.

"She got really upset and she started talking about, her kids leave her 50 percent of the time," Dubrow says.

The show then flashed to dinner where Barney's crying, "I didn't sign on to be a part time mom."

"And if she had a kid with you, you wouldn't leave," Dubrow tells Judge.

"Tamra has always said that it's Eddie that wants a baby, but it's really Tamra," Dubrow tells the camera.

"And I don't really think she's being honest with Eddie about that."

"She cried, she got really upset," Dubrow tells Judge.

"She was very emotional about it. And then I got it."

Dubrow then tells her husband on the way home from the party, "I'd rather have one fabulous friend, than a dozen pieces of sh*t."
