Kim Richards is most certainly related to the Hiltons, and, naturally, so is her sister Kyle! Kathy Hilton, the mother of Paris and Nicky, is the daughter of Sharon Dugan and Laurence Avanzino. After her parents divorced, Kathy's mother remarried Kenneth E. Richards, and had two more children, Kim and Kyle — Kathy Hilton's half-sisters! Kathy is married to Richard Hilton, of the hotel Hiltons. She and Richard have two sons — Conrad and Barron — as well as their two party-loving daughters. Speaking of, it was through her niece Paris Hilton that Kyle RIchards had her first experience with reality television; she guested on Paris's two reality shows, The Simple Life and My New BFF.
