"No, I don't think they will," Margaret said of a divorce. "I think Teresa's super traditional and I just don't think she'll do it."
The deportation order -- which, Margaret said, left her "devastated and surprised" -- requires that Joe, 46, leave the United States for Italy immediately after serving his 41-month prison sentence for pleading guilty to fraud.
ET caught up with 46-year-old Teresa last month, who said that there was no way she'd consider a divorce.
"We're going to be a family, and we're going to fight this and get through this," she said. And fight it they have, with Joe filing an appeal to the order less than a week ago, something Teresa had previously said they were "going to get through."
"We are not even thinking about [whether we'd move to Italy] right now," she told ET. "We're going to take it day by day. We're going to take it one step at a time."
While she's trying to remain positive and not talk about the order yet, Teresa admitted that the main reason they plan to fight the order is their children -- Gia, 17, Gabriella, 14, Milania, 13, and Audriana, 9. "What comes first is our daughters and we're going to fight this," she said.
"It's been a lot for kids to take this all in," she added. "It's sad for the children because they're innocent in all of this, and they're probably thinking, 'Why is this happening?'"
