Vicki Gunvalson Is 'Extremely Hurt' by 'RHOC' Cast Saying She Took 'Four Xanax' at the Reunion!

The Real Housewives of Orange County are making some shocking new claims against co-star Vicki Gunvalson.

Following Sunday night's shocking conclusion to the RHOC's Season 10 Reunion special, Heather Dubrow, Shannon Beador and Tamra Judge allege that Gunvalson was heavily impaired during their spill-all sit-down with host Andy Cohen.

"She would contradict herself with every answer. Was it the Xanax?" Heather asked her RHOC co-stars during the first episode of her new podcast, Heather Dubrow's World, on Tuesday. "She told us all, she took Xanax. She was worried, she was nervous. And I just feel like, when you have the truth, you're not nervous."

"She had taken four Xanax, is what I heard," Tamra claimed. "And I was in her makeup room, briefly, and her makeup girl was saying, 'No, don't take another one.'"

Shannon added, "Her eyes were rolling to the back of her head!"

At the reunion, Vicki claimed to only have taken "half a Xanax" before filming began, so what does the "O.G. of the O.C." have to say about these allegations?

A source close to Vicki tells ET these latest allegations are "ludicrous," and that Vicki "definitely did not take four Xanax at the reunion."

"Vicki is extremely hurt by these allegations," our source says.
