During Sunday night's episode of The Real Housewives of New Jersey, Melissa Gorga's ex-best friend made an explosive claim, saying Joe Gorga's wife allegedly hooked up with a former boyfriend in a car in a parking lot.

Melissa decided to confront Jan during Teresa Giudice's launch party for her Milania hair care line -- but what viewers saw on TV was only the tip of the iceberg. Jan, who was once one of Melissa's bridesmaids, vented about the episode, making even more claims about Melissa being a "liar" and "backstabber."

"Lies lies and more lies!!! I was begged to go there," Jan said in a comment obtained by EnStars, adding that Bravo production made her show up to the taping.

During the episode which aired Sunday Aug. 18, the confrontation got heated. "You did meet your ex," Jan snapped. "You used me as an alibi. I’m done lying for you! You have a lot of skeletons under your bed."

While Teresa stayed silent, Melissa fumed that her friendship with Jan was "done."

Jan continued to rant on her Facebook page, hoping to expose Melissa as a fraud.

"The best part is she went there to confront me... Anyone who knows Melissa can clearly see she was lying and sh*tting her pants," Jan wrote. "Btw (sic) Melissa, you need to hire a new acting coach because you're way too transparent."

"It's funny how she calls me the backstabber, but she's the one who pulls me into this, so she can have a story line. We all know she has NOTHING going on without this," she added.

She continued to rage on, specifically calling out her former BFF. "And Melissa should I tell the real story how u got on the show??? You back stabbed your own family so you can have your "5 minutes of fame". This is actually comical now!"
