Is it even possible that Melissa Gorga and Teresa Giudice's tumultuous relationship has gotten even worse since the filming of "The Real Housewives of New Jersey" season four finale?

According to Melissa, Giudice (her sister-in-law) set her up at the Posche Fashion Show and since then, she alleged, Giudice has tried to sabotage her. 

For a full season four finale recap, click here. A brief synopsis: former owner of Lookers Gentlemen's Club, Angelo Voorhees, approached Melissa Gorga and said, ""Hi Melissa, you remember me right?" during Kim D.'s fashion show for her Posche boutique.

After some awkward small talk, he left.

Giudice took Melissa into the ladies' restroom and confronted Melissa. She told Melissa that Voorhees was spreading rumors about her, claiming she used to be a dancer at Lookers.

She then said, "I know it's not true" and Melissa admitted she was a bartender at Lookers, which she said was technically a bikini bar. Melissa said she only worked there for a week because she hated it.

"It was vindictive and disgusting," Melissa told Us Weekly magazine (according to WetPaint Entertainment). "What Teresa did was like stabbing a knife in my back."

But why would Giudice want to embarrass Melissa and ruin her reputation? 

"It's so hard for me to put myself in Teresa's shoes because I'd never try to hurt anybody," Gorga said to Us Weekly. "Maybe she thought my husband didn't know that I worked there. Maybe she was trying to hurt my marriage. Maybe it will make her happy when everyone is as miserable is Teresa is. That's a sick individual. It's even sicker that she would put this on national TV." 

Melissa accused Giudice of trying to ruin her club appearances and stop them from even taking place! 

"I had some club appearances booked and she called the owner and said, 'Don't give her another appearance. Don't pay her.' The owner called me up and was like, 'Teresa is literally screaming at me.'"

"She's trying to hurt us as much as she can financially," Melissa added.

After the Posche fashion show (it would make more sense to call it a "showdown"), Joe sent Giudice a text messaging stating, "You're dead to me."

Melissa claimed Joe, Giudice's brother, is still "beside himself." "He has a really hard time forgiving her because he's so sick and tired of her bashing us," she said.

Will Melissa and Giudice ever make amends? According to Melissa, she is "officially done" with Giudice.

 "This is one of the worst betrayals of my life."
