Hilary var på 20th Anniversary Party for Kentucky & USA Harvest i Open Hand Kitchen i Society of St. Vincent de Paul i Louisville den 25 Augusti.
Earlier, at the lunch, Curtis said of Duff that "any father in the world would be proud to have her as a daughter."
Duff, near tears, called the other people in the room ? most of them program volunteers or donors ? "inspirations."
"I?m overwhelmed to be in a room of so many accomplished adults," she said, adding that she got involved with the program because her mother raised her to "stand for something."
