The final sit down between the four original "Mob Wives" cast members Renee Graziano, Drita D'Avanzo, Carla Facciolo and Karen Gravano is set to air tonight in the last-ever reunion special. As the series comes to a close, it's the last chance for the OGs to put everything out on the table and settle their differences - once and for all.

During the last season of the hit VH1 reality TV series, old beef resurfaced between D'Avanzo and Gravano. Through the series, the women have continuously fought over D'Avanzo's husband Lee, whom Gravano dated as a teen, and D'Avanzo accused Gravano of still being obsessed with Lee in a previous episode. During the explosive season finale, they confronted each other in a sit down. Moments into their heated discussion, they lunged at each other from across a table and were separated by security.

In a sneak peek for the upcoming final reunion episode, fans are allowed to watch behind-the-scenes footage as the ladies prepare for the taping. They each sit in separate hotel rooms with their glam squads, getting their hair and makeup done as they watch video packages made up of clips from throughout the series, and some never-before-seen footage gets Gravano and D'Avanzo worked up.

Gravano watches a clip of D'Avanzo talking about her and her father, where D'Avanzo accuses Gravano of dragging her father's name into the drama.

"My father?!" Gravano says, talking to the TV screen. "Who brings up the men, you p---y b---h! I'm really glad that I get to see this because this girl is such a f--king punk liar b---h."

D'Avanzo watches a clip of Gravano calling her a "rat" - a mafia term for someone who betrays someone's trust. D'Avanzo gets up to apply her lip gloss in the mirror and vents to her producer.

"I'm not sitting here watching people rip me and I can't do nothing about it," D'Avanzo says. "You let them talk s--t and protect them. You can't do that. You created little f--king monsters. Little wannabe gangsta tough guys."

Meanwhile, Gravano vents to Graziano as they share a car on the way to the reunion studio.

"Drita, I've had it with her, f--king fake fraudulent b---h," Gravano says. "She thinks that like going around, 'I'm the boss. I run Staten Island' - like is this b---h a f--king psychopath?"

"Listen, the only people that don't like the truth are living f--king lies," Graziano advises. "Remember that."

Watch the full sneak peek below and be sure to tune into the last-ever "Mob Wives" reunion special, airing Wednesday, March 16 at 8 p.m. on VH1.
