Dissed! 'RHONJ' Cast Not Invited To Major Network Event — Show Cancelled?

Have the cast members of the Real Housewives of New Jersey become outcasts?

RadarOnline.com can exclusively reveal that the Bravo show is not represented at the NBC Upfronts, an important network event during which the media is introduced to the upcoming season's shows on Bravo.

"Amber and Jim weren't invited to the NBC upfronts this year," an event source tells RadarOnline.com.

In fact, "There are cast members from Atlanta, Beverly Hills, New York, and Orange County," the tells RadarOnline.com, adding, "no one from New Jersey cast is on the list."

The revelation may not bode well for the show, which lost its major star, Teresa Giudice, this year when she was thrown in the slammer for fraud.

"I think they weren't invited because the Real Housewives of New Jersey is not going to air this summer," the source says.

As RadarOnline.com reported, Bravo finally made the decision to continue filming the reality series without imprisoned Giudice, but the rest remains up in the air.

"The show will absolutely go on without Teresa," a source close to the cast told RadarOnline.com, adding "no formal dates have been made for filming to begin because producers are still looking for potential new cast members."
