Although the pair got along fairly well throughout the sixth season of the Bravo reality show, all bets were off when the two came face-to-face during the three-part reunion special.

“Manzo sniped that she wished someone would use glue and concrete to keep Laurita’s mouth shut,” an insider told Radar Online on Oct. 22. “Jacqueline has a lot going on in her life, including dealing with her autistic son, and Melissa jumped to her defense."

Gorga joined the cast of The Real Housewives of New Jersey during the show's third season. She and cast mate Kathy Wakile replaced Manzo and Danielle Staub, who left the show after season two.

During season five, Gorga and Manzo began starring on the series together for the first time. Unfortunately, Teresa Giudice's sister-in-law, Gorga, and close friend, Manzo, didn't end up as friends. Instead, they completely turned on one another and are no longer speaking.

“There is no love lost between Melissa and Dina,” the source noted. “Melissa wants nothing to do with Dina, and questions anyone that can’t get along with Jacqueline.”

The Real Housewives of New Jersey's three-part season six reunion special begins next Sunday night at 8 p.m.
