Nicky Hilton swung by the Century Regional Detention Center in Lynwood on Saturday for her weekly visit with big sister, Paris. She came with her boyfriend David Katzenberg and another friend and left behind a mysterious small red package with the correction officers. A gift for big sis? Meanwhile, their parents, Rick and Kathy also came by later for Father's Day, though as Rick told reporters, "It's not one of my best." According to mom Kathy, Paris made her father a "beautiful card with his picture." Maybe Nicky's present was crayons?
