"Izzie … Lizzie …" Gunvalson said to Rovsek, as the housewives took a limo to a holiday dinner.
"You can call me Elizabeth since you can't keep it straight," said Rovsek, none too amused by Gunvalson's instant attack.
"Lizzie seems like a little girl with pigtails," Gunvalson said. "Why can't we call her an adult name?"
And the holiday surprises kept coming: When Rovsek stated she was a former valedictorian and beauty queen, Gunvalson remarked, "How many people were in your class, because I could be valedictorian of a class of one," before yelling, "I don't ever want to be a pageant girl."
"You don't have to yell at me. You're not very friendly," Rovsek stated. "They say insecurities are very loud."
Tequila couldn't even help melt the ice at dinner.
When Gunvalson ordered shots for the table, and everyone got one save for Rovsek, she was none too happy, telling Gunvalson it took nerve to do that.
"I ordered six!" Gunvalson yelled. "I don't like her disrespect."
Perhaps Gunvalson should have brought along new friend Shannon Beador's energy workers to dinner.
Beador not only brought her feng shui expert to Gunvalson's insurance offices to keep the wealth from "leaking out the door," but she also took Gunvalson to her energy healer, Dr. Moon.
"I can show you how to scream," said Dr. Moon.
"Oh, I got that down," joked the oft-yelling Gunvalson, who then accused the doctor of touching her backside.
"Of course he put his finger in her butt," deadpanned Tamra Barney. "His name is Dr. Moon."
The Real Housewives of Orange County airs Monday (9 p.m. ET) on Bravo.
