'RHONJ': More Drama for Season 4 Premiere

New Jersey's favorite housewives will be back on the air this Sunday with the Season 4 premiere of The Real Housewives of New Jersey at 10 p.m. on Bravo and if you thought last season was a snoozer without the drama of Danielle Staub, get ready for even more tension as several websites and blogs are reporting that this season will be anything but quiet.

Even in the official trailer for the season on Bravo's website, called "Things Are About to Explode in Jersey," the housewives are seen yelling at each other, tossing their hair and pointing their fingers in each others' faces.

"There are really evil people out there and sometimes they come in the shape of your friends," Teresa Giudice, a Towaco resident, said in one of the interviews in the preview.

But according to the preview video, drama is not all that viewers can expect. There are comedic moments shown as well, like a trip to the Golden Gate Bridge in San Francisco where Melissa Gorga and Giudice discuss why the bridge is called "Golden" if the bridge is orange.

Several local scenes were filmed as well, including one in Montville at the where Gorga learns some dance moves and prepares to perform before a live audience on the show.

At the heart of the drama is the ongoing tension between Giudice and her brother and sister-in-law, Joe and Melissa Gorga. But continuing drama between Caroline Manzo and Giudice that began when Giudice wrote some comments that offended Manzo in will escalate. According to the Huffington Post, the real reason Jacqueline Laurita did not attend the Season 3 reunion show will also be revealed this season.

Lauren Manzo will struggle with weight loss while Jamie Manzo, the brother of Caroline and Dina Manzo, will have a wedding with his gay partner. According to Hollywood Life, Laurita, who has long had troubles taming her wild daughter, Ashley, will reach a resolution that will shock viewers during Sunday's premiere.

The castmates will also take a trip to Napa Valley, but the drama will cause the trip to be less than relaxing, at least for housewife Laurita. Even Joe and Teresa Giudice are expected to have some tense moments between each other. As was teased on the Season 3 reunion show, the Season 4 drama is sure to involve all castmates.

"When you associate with scum, you become scum," Kathy Wakile said in the trailer.

NJ.com reported Tuesday that several of the housewives will attend a premiere party in Hoboken Sunday night. Confirmed guests include Caroline, Chris, Albie and Lauren Manzo, Greg Bennett and Jacqueline and Chris Laurita, but it is unknown whether Giudice will attend.
