Marc Anthony was an hour late for a power lunch with Bank of America private wealth manager Jane Heller, who has managed funds for clients including Martha Stewart and George Steinbrenner. The single-again Latin crooner was scheduled to have lunch with Heller at noon at the Four Seasons restaurant on East 52nd Street Tuesday afternoon, but — in a mistake others have made — went instead to the Four Seasons Hotel on East 57th Street. Heller waited for him alone in the restaurant’s Grill Room for a half-hour before she and Anthony each realized they were at different addresses. Anthony, too famous to walk, summoned his driver and rode five blocks to the restaurant, arriving at Heller’s table at about 1 p.m., sources said. The singer’s divorce from Jennifer Lopez is still pending, and sources speculated Heller could be helping Anthony divvy up his assets. A rep for Anthony told us, “He had a few meetings in the city to discuss current and future plans.”
