Celebrity The Giuliani Divorce By Staff Author Published on March 24, 1998 12:00 AM Share Tweet Pin Email So why doesn’t New York City’s First Lady Donna Hanover just move out of Gracie Mansion? That’s the question posed by PEOPLE in its latest cover story, on the bitter divorce between Hanover, 51, and Mayor Rudolph Giuliani, 57. Hanover has demanded that the courts prevent her estranged husband from bringing his very public girlfriend, Judi Nathan, 46, into the mayoral residence. Hanover’s attorney, Victor Kovner, says his client and Giuliani, who formally filed for divorce last December, agreed to share the mansion “for the sake of the children” until his term expires on Dec. 31. (The kids are Andrew, 15, and Caroline, 11.) “They don’t agree on much,” Kovner tells PEOPLE, “but there’s no disagreement on that.” Besides, the $750,000 Upper Eas t Side apartment the family shared before Giuliani’s election in 1993 is sublet through the end of the year. And considering the price of East Side real estate, public housing may not look so bad: A three-bedroom apartment in the neighborhood sells for about $1 million; renting one could cost $10,000 per month.
