Teresa Giudice has the perfect recipe for making enemies
The Real Housewives of New Jersey
's third season came to an end Sunday with Teresa offending her costars with comments she made in her second cookbook, Fabulicious!
Taking shots at her sister-in-law Melissa Gorga (who was steamed to read she allegedly "copied off" Teresa's taste in shoes and porch chairs) and her cousin Kathy Wakile (who spotted a comment she didn't like about making lame jokes about Teresa) isn't new but taking aim at pal Caroline Manzo certainly is.
, Teresa questioned Caroline's method of making meatballs, called her one-sixteenth Italian and criticized her son Chris's idea for a stripper-run car wash.
"When it served her purpose, she was my friend," Caroline Manzo said on the finale, adding that there was "no legitimate reason" for Giudice to make remarks at her expense in a cookbook.
Teresa told former friend
Jacqueline Laurita on the show the comments were meant as a joke.
And she defended herself in a post on teresagiudice.com
: "Ask yourself when you watch the episode: Why would I purposefully insult someone I had only ever been nice to – even nice to behind their back, unlike how they were to me?"
She also says that Caroline may be jealous of her cookbook.
"I remember when I was writing my very first book proposal, Caroline was also trying to sell her own cookbook (and 5 other Housewives were too!). Caroline told me I was doing it wrong, that I wasn't smart enough, that I didn't have the right agent, the right co-writer, the right anything," she says. "I took her criticism like I always do, with a smile, and did what I wanted to anyway. And my book got picked up. Caroline's didn't. Not one publisher wanted it."
The New Jersey
reunion is sure to bring even more fireworks, according to a clip that aired Sunday night on Watch What Happens Live
