Jennifer Graziano, creator of VH1's Mob Wives, is shaking things up in season 4 with the addition of new cast members — and plenty more drama. "They're all trying to feel each other out, get to know each other so in the beginning you can see that they're testing each other, who's who, what's what," Graziano told Uinterview exclusively. "We're definitely in for a lot of surprises. The ones that you thought that were not kind of fiery, really are. Even I was taken aback by that."

Working with her own sister, Renee, who stars on the series, has presented some challenges for Graziano. "I walk the fine line because my sister is on the show so it's kind of hard sometimes to see what she goes through," said Graziano. "But she's an open book and she will not let us turn the cameras off regardless."

Mob Wives: New Blood airs Thursdays on VH1, 10 p.m. EST.
