The reason for their departure from the show is related to money. Producers did not want to pay the ladies, which led to their decision to not return for the upcoming season.
The creator of Mob Wives is Jen Graziano, who happens to be Renee’s sister. Jen is also known to be good friends with Ramona and Karen.
Renee took to Twitter to express her thoughts on the matter. She referred to the ladies as “greeting” and it can be assumed that she was not pleased with their decision to leave the show.
