Maxime de La Falaise married, as her second husband, John McKendry, curator of prints and photography at the Metropolitan Museum of Art, who died in 1975. During the marriage it has been suggested that he had an affair with photographer Robert Mapplethorpe, while she had one with J. Paul Getty III, artist Max Ernst, and film director Louis Malle. La Falaise is said to have aided Mapplethorpe's entry "into high society, European and American."
