Aunt of heiresses Nicky and Paris Hilton, this sassy California native was born into an acting family. She landed her first role at the age four in Disney's Escape to Witch Mountain, where she played the younger version of her sister, child actress and fellow Beverly Hills Housewife Kim Richards. Acting gigs aside, Kyle says her greatest passion is being a mother to her four daughters. Her motto? "If you obey all the rules, you'll miss all the fun."
