Fashionable couple Anne and Mario Grauso have called it quits after 18 years of marriage. Anne confirmed the split to Page Six and called her separation from her husband, the president of Vera Wang, “amicable.” They have a home in upstate Millbrook. Anne, who recently was profiled in Harper’s Bazaar after she dropped 60 pounds, said she’s moved into a “fantastic” renovated warehouse in Williamsburg. The Grausos have a son, Henry, 14.
