Teresa continues to hold a grudge against Kathy, even after their heart to heart last week. And Teresa may be blind to another important relationship blowing up in her face.

Kathy Wakile thought she and Teresa Giudice were on the cusp of rekindling their friendship on the Aug. 19th episode of The Real Housewives of New Jersey.

That fire burnt out quickly, when Teresa mentioned everyone BUT Kathy in her toast at the group’s final dinner.

“Chris and Jacqueline I just want to thank you for inviting us, we had a wonderful time. And Joe and I loved spending time with my brother and Melissa. And we love you guys. Oh yeah, and happy 50th to Caroline. And that’s it.”

Kathy gives a shrug of her shoulders, but admits she “felt embarrassed.”

Even after Teresa confronted Kathy about her comments at the book signing in last week’s episode, she just won’t drop it.

The housewives’ California adventure was going so well up to that point, with most drama held to a minimum. Friendships were being mended and families were coming together.

Teresa and Melissa Gorga continued their bonding. Melissa even teased Teresa about videotaping her and husband Joe Giudice having sex in the vineyards, because Teresa’s such a “media-whore.” Surprisingly, Teresa found the joke funny.

Over in the Manzo/Laurita RV, the families discussed Jacqueline Laurita‘s own burying the hatchet conversation with Teresa. Caroline Manzo, who has avoided Teresa the entire vacation, is still skeptical and admits she “is done” with Teresa’s antics.

It wasn’t all play on this vacation. Chris Manzo had to take care of some business, trying to partner with a couple of the vineyards and bringing their product back east.

Of course, not everyone realized the seriousness of the situation. The Giudice and Gorgas couldn’t help from making wise-cracks and inappropriate comments throughout the vineyard tours.

But the woman at the Levendi vineyards did get a kick out of Teresa and Melissa’s recounting of their own grape-stomping experience. “Just like Lucy and Ethel,” Teresa said.

The most touching moment of the night came when the Manzo family surprised mother Caroline for her 50th birthday with a lovely dinner directly overlooking the vineyard. Each of the kids gave a heartfelt speech, leaving their mom in joyful tears.

The happy occasion was briefly interrupted when Teresa went to confront husband Joe about a mysterious phone call. Here’s what SHE missed:

“Hold on, here she comes, my b**** wife. She’s such a c***,” Joe tells the person on the other line. He covers by telling Teresa it’s one of his workers and Teresa accepts that answer.

The two then slip into the vineyard for a little hanky-panky — because God forbid Caroline have all the attention on this evening. I guess Teresa will continue to stay in the dark about Joe’s strange phone call.

Prepping for their final dinner, Teresa visits Jacqueline’s “salon.” The two have a little girl chat, but avoid any serious topics. Jacqueline does suggest Joe speak with her husband Chris Laurita and clear the air about their issues.

On the other side of the suite, Caroline visits Kathy’s “salon.” The two discuss, who else, Teresa. Kathy wants to know about Jacqueline and Teresa’s conversation, but Caroline remains suspect and doesn’t think the relationship is at all healthy.

Finally as all the families sat down for dinner, it looked like this trip was going to end on a happy note. But Teresa’s “mean” toast, as Caroline called it, soured any chance of the housewives’ friendships growing any stronger.

How about you Hollywoodlifers? Were you surprised by Teresa’s toast, or is it just more of the same old Teresa rudeness?
