Here's a link to a great recap site endorsed by the ladies of Mob Wives: http://mobwives.blogspot.com/
Natalie started the drama. She tweeted incessantly at Karen, calling her Miss Piggy, fat, a rat and basically slamming her whole family before she even met Karen.
Karen retaliated with a picture she got from Nat D (not hacking Gnatalie's mom's FB Page). This set off Gnatalie's "dead beat Mom" tweets to which Karen's daughter got involved by tweeting to Gnatalie to leave them alone. This is why Karen was so upset and the girls rallied around her. Gnatalie did not admit to any wrong and kept saying that Karen started it, when she did not.
Basically a hair pulling cat fight over social media, which was painful to watch and kind of pathetic.
