This sassy California native was born in Hollywood, into an acting family. She landed her first role at age four in Disney's Escape to Witch Mountain, where she played the younger version of her sister, child actress and fellow Housewife Kim Richards. Her other sister is Kathy Hilton, mother to Nicky and Paris Hilton. Kyle's TV credits include Little House on The Prairie, Carter Country, Down To Earth, and E.R. Film credits include Halloween, and The Watcher in the Woods. Kyle is an avid advocate for the fight against cancer, even completing a 68-mile bike marathon last year to raise money to help fight the disease. Kyle is married to the love of her life, Mauricio Umansky, one of the nation's top realtors. Up next, Kyle is starring in the Lifetime original movie, Deadly Sibling Rivalry, and is also developing her own handbag line, working on her new lifestyle book, and creating her own skin care line with famed Beverly Hills spa Vera Bella. Her greatest passion, however, is being a mother to her four daughters: Farrah (22), Alexia (15), Sophia (11), and Portia (3). Kyle believes "If you obey all the rules, you'll miss all the fun."
