Melissa and Joe confront the woman behind the cheating scandal in explosive sneak peek.

on Sep 13, 2013 - The Dish

After the trip to Lake George and their spiritual journey in the Arizona desert, things have been looking up for the notoriously tense relationship between the Gorgas and the Giudices on the Real Housewives of New Jersey. But while Teresa and Joe have seemingly made peace with Melissa and Joe, questions have lingered for the Gorgas: Who was really behind the most recent bunch of rumors claiming Melissa hasn't been faithful to her husband?

In a sneak peek at next week's explosive episode, some potentially destructive information finds the light of day. Asked point-blank by the Gorgas who asked her to dig up dirt on Melissa, Penny Drossos says, "It was your sister."

What's more, Penny claims Teresa asked her to find the info and then make sure the Gorgas knew trouble was brewing. "She said to me, 'Can you confront my brother about it?'" Drossos claims.

So why did Penny lie and claim she wasn't friendly with Teresa at the recent launch party? And why does Penny's husband John Karagiorgis (who's sent harsh tweets about Melissa) allegedly have texts from Teresa in his phone? See how the rest of the drama unfolds on Sunday night's Real Housewives of New Jersey, titled "The Blonde Drops a Bombshell."

What do you think of Penny's revelation? Do you think Teresa is behind the rumors? Tell us in the comments.
