Danielle Staub has reportedly been fired and won’t return for a new season of “The Real Housewives Of New Jersey”, but she was quickly replaced by another controversial housewife, Melissa Gorga, who is Teresa Giudice’s worst enemy and her own estranged sister-in-law.

Melissa is married to Giuseppe Gorga, Teresa’s younger brother, for more than six years and they have three children together, two boys and a girl. Teresa believes Melissa, who worked as a secretary for Giuseppe before he put a ring on it, is a gold-digger and is threatening to leave the show if Melissa joins the cast.

“When Teresa got word that her sister-in-law was asked to be part of the show she said, ‘If she’s going to be on the show, then I’m not going to do it,” a family source told RadarOnline.

“Teresa and Melissa don’t get along…They don’t speak,” a Giudice family friend added. “She doesn’t want to be on the show with her…I don’t think that she’s made her final decision and told them [Bravo] that yet.”

The family friend added: “I think they’ll probably just bring more drama, and if Teresa is on the show it would be a competition. They’ve always been in competition. Melissa will stand up to her on TV. She’s a nice woman, but Melissa will give her a run for her money if Teresa busts her balls.”

A source close to Gorga added: “I don’t believe she’d want her brother and sister-in-law on the show. She’d rather do it without family. But it’s up to Bravo, not Teresa.”

Teresa and her husband Joe Giudice are currently facing some very difficult financial problems as they declared bankruptcy. So Teresa cannot just walk away from Bravo’s hit show. She will also have to deal with the fact that her sister-in-law leaves in a house twice the size of her mansion and is able to spent tremendous amounts of cash in futilities. OUCH!

Teresa will have to learn how to live with a bruised ego!
