The feud rages on between the houses Gorga and Giudice over in New Jersey. Teresa's strained relationship with her brother Joe and sister-in-law Melissa seems to remain unresolved, because apparently Joe wasn't invited to his niece (and goddaughter) Gia's birthday party this weekend!

After he failed to tweet Gia happy birthday (for the record, Dina Manzo and Kathy Wakile both did) a fan tweeted the hunky Househusband, "Joe I think you r a sweetheart, but did u wish Gia Happy Birthday Sunday?"

He tweeted back, "Of course we did. Wish I had an invite." As you can imagine, Gia and Teresa were tweeting pics of the party all day long, so Tio Joe keenly felt the sting of his snub.

Well, we have to assume Teresa was just trying to avoid an extremely distasteful, and frankly awkward cryfest — a la Melania's infamous birthday party last year — during which Gia performed a song she had written to express her sadness over her fighting famiglia.

We need a glass (read: bowl) of pinot just thinking about it.
