They may be rookies, but the three newest Real Housewives of New Jersey certainly brought out old-school Jersey drama on Sunday.
The housewives attended a First Responders-themed costume party, only to witness a five-alarm fire breaking out when hostess Nicole Napolitano confronted Amber Marchese about the rumors that she heard Marchese was spreading about her being a homewrecker.
Napolitano’s twin, Teresa Aprea, got Amber’s embers burning when she approached her and then stalked off. Marchese followed and – with a fiery “Let’s go!” – insisted they go elsewhere to talk, and the scene turned into an inferno.
“I’m not your dog,” Napolitano snapped. “Do not do that, Amber!” Fists, wine, words and glasses flew, with the twins turning on their former friend.
“Get off me!” Marchese shrieked.
As her hair was being pulled, Marchese screamed at Napolitano, who was tossing the party with boyfriend Bobby, “That’s why he won’t marry your ass!”
“Nicole was my friend,” said a distraught Marchese, who stormed out of the party furious at the twins and just as angry at Melissa Gorga, who fueled the fight by telling the twins what Marchese felt she had told her in confidence. “I hope you’re happy, Melissa!”
And then it was the husbands’ turn.
