Teresa Giudice, Jacqueline Laurita, Caroline Manzo and Dina Manzo attend the after party for the opening night of 'My Big Gay Italian Wedding' at Etcetera Etcetera restaurant.

Don’t blame it all on Danielle StaubDina Manzo claimed she left “The Real Housewives of New Jersey‘s” second season in June because of Staub, the show’s antagonist, but a source close to the 40-year-old Manzo tells us she split because of money, too.

Jacqueline Laurita revealed at the after-party for the opening night of “My Big Fat Gay Italian Wedding” (in which the ladies guest-starred) that she thinks “there were a lot of reasons Dina left the show.”

Our insider tells us one reason was her disagreement about the network’s financial setup and the salaries for the gals.

While the blond single mom hasn’t spoken out about the topic directly, she did mention at the fete, held at Etcera Etcera restaurant, that it wasn’t her “ideal contract.”
