Real Housewives of New Jersey Season 4: Teresa Giudice Explodes!

Throw down in the Garden State!

The Real Housewives of New Jersey aren't getting any kinder and gentler as season four of the Bravo reality hit begins.

At the center of the storm? Teresa Giudice, naturally.

In the just-released trailer, Giudice clashes with just about everyone: Caroline Manzo (and her sister, former castmate Dina), Jacqueline Laurita and sister-in-law Melissa Gorga.

"There are evil people out there – and sometimes they come in the shape of your friends," Guidice snipes.

Says Gorga in one confrontation: "Run away, coward. Like you always do!" (Gorga and sister-in-law Giudice are at odds over Gorga's alleged past as a stripper.)

Says Laurita, who skipped the season three reunion for reasons unknown: "F--k you Teresa. I see you for exactly who you are."

"When you associate with scum, you become scum," Kathy Wakile muses.

"I can't even look at you!" Caroline Manzo says to Teresa, who revealed a secret about her sister Dina.
