Two people who are almost certainly coming back to the new season are Real Housewives veterans Teresa Guidice, who is currently serving a prison sentence for fraud, and Melissa Gorga, a source close to the show tells ET.
Jacqueline Laquita is also likely to return, the source tells ET, while new additions Amber Marchese, Teresa Aprea and Nicole Napolitano – who joined in season six – have not been officially asked to come back, according to a second source.
Dina Manzo, who returned as a full-time castmember in the previous season, will not return. Kathy Wakile and Rosie Pierri will be back as "friends" of the main cast.
Rumors have swirled that the wife of former NFL star Tiki Barber, Traci Johnson, had been approached to appear on The Real Housewives of New Jersey, though she has not officially signed on.
At one point in time, Bravo also sought out Nicole "Snooki" Polizzi and Geraldo Rivera's wife Erica Levy to join the cast. Levy declined.
The season seven cast is expected to be finalized by the end of September, and filming will begin shortly afterward. Cameras will also be rolling when Giudice returns home from her prison sentence on Dec. 23.
