Melissa Gorga stormed out of Teresa Giudice's 12th birthday party for her daughter Gia in the latest battle in the long-running family feud.

Viewers saw the fireworks on Sunday night's The Real Housewives of New Jersey after Teresa's brother Joe Gorga decided not to go to the party and wife Melissa went instead -- but got ambushed by her sister-in-law and her friends. Teresa and her posse accused Melissa of not visiting Teresa and Joe's father after he was rushed to the hospital for pneumonia in his latest medical crisis.
