Here's the scoop:
Bravo executives weren't quite too thrilled about Jacqueline missing in action during the season 3 reunion, but it was her excessive tweeting & exposure of [season 4] key storyline developments which led several viewers to believe that her role as "cast member" was discontinued and to be replaced by Kim Granatell.
That would technically make plenty of sense (in a perfect world), but unfortunately it's not one bit true and I'll explain why. Season 4 has already been filming since before the season 3 reunion even aired, and Jacqueline has been filming along with the rest of the current cast - Melissa, Kathy, Teresa, and Caroline.
Bravo has been very strategic for filming the new season 4 while the current season 3 is playing on air, it builds more drama amongst the cast for the show and instigates false rumors - all of this is such a great recipe for higher ratings.
There have been several accusations against Jacqueline for exposing Joe Guidice's secret relationship with his mistress, Davana Medina - but Kim Granatell (along with Tom Murro) is actually taking the credit for releasing the pictures of Joe & Davana to the public.
Now that Teresa is portrayed as the new Danielle for the next season, everyone wants to know what exactly is going to happen between the cast. Caroline has accused Teresa for her current separation from Dina, and Jacqueline has also turned her back on Teresa as well - but that's okay, because Teresa is allegedly set to record her own cooking show after she's done filming for season 4 of Real Housewives of New Jersey.
