Real Housewives of New Jersey: Teresa Guidice and Caroline Manzo’s Feud Explodes

Oh, how things have changed!

In a sneak peek at part one of The Real Housewives of New Jersey reunion show, one-time friends Caroline Manzo and Teresa Giudice are at each other’s throats.

The only two original Housewives in attendance (Jacqueline Laurita refused to participate) shed tears, shouted insults and accused each other of lying and their turning backs on their families. They also tackled Teresa’s husband Joe’s legal problems and Caroline’s relationship with her sister, Dina Manzo, who quit the show in season 2.

How did it all go so wrong for two women who have traveled together, spent holidays together and weathered Danielle Staub together?

On the season finale, Caroline took offense when Teresa dissed her recipe for meatballs and said she was merely one-sixteenth Italian in her latest cookbook, Fabulicious!.

“When it served her purpose, she was my friend,” Caroline said. Teresa defended her comments, saying they were meant as a joke, and later, in her blog, said Caroline was jealous of her because that she’d scored a cookbook publishing deal while “not one publisher wanted [a cookbook by Caroline].”

But is this explosive drama really all about recipes and insults?

It seems like this fresh beef goes deeper – and you can be sure the devilish details will come out in the two-part reunion, which begins Sunday (10 p.m. ET) on Bravo.
