EXCLUSIVE VIDEO INTERVIEW: Danielle Staub's New Pal Turns Against Her

At first the women got along well. “I liked her - I thought she was a great mom. I went to her house, we went out, she made dinner a couple of times,” explained Kim. “I introduced her to other friends of mine, we had a nice friendship.”

But as time went on, Staub alienated Kim -- especially when the cameras weren’t rolling.

“If it’s not Danielle’s way then she’s not happy. You can’t sit down and discuss logic or things that are going wrong in your relationship or friendship because she’ll cut you off and chew you down.”

Eventually Kim said enough is enough, and cut all ties.

“I couldn’t live like that, I was walking on egg shells.” She said. “I had to mince my words – ‘Could I say this? Could I say this?’ It was really difficult,” complained the mother-of-three, who separated from her husband seven years ago.

“She wants attention like immediate,” says Kim, recalling one prima donna public performance from Danielle when the pair was out shopping. “One day we were out in Neiman Marcus and she said, ‘I don’t carry bags, they can carry the bags for me or they can send them to my house.’

“She doesn’t have money, but she returns everything,” she added.

Kim says it is Danielle’s actions more than her words that sting. “She really never said anything that would kill me, it’s the backstabbing, it’s the sneakiness, I just said, ‘Where’s the loyalty? Where’s the trust?’ “

“It’s definitely high school stuff, we are like high school.”

Kim -- who’s vying to be the next full-time housewife on the show -- admits that the cattiness is what makes the Real Housewives must-see-TV.

“Who’s fighting and who’s backstabbing? That’s what sells.”

Danielle needs all the friends she can get right now as she struggles with new personal problems.

RadarOnline.com exclusively reported on Monday that Danny Aguilar, a convicted felon who was once charged as Staub’s co-defendant in a drug conspiracy case, called the Real Housewives of New Jersey star on Sunday night demanding $100,000 he says she still owes him for bailing her out years ago with some big time drug dealers.
