Kourtney was born in Los Angeles, California as the eldest of four children of Kris Jenner (née Kristen Mary Houghton) and attorney Robert Kardashian, with siblings Kim Kardashian West, Khloé Kardashian, and Rob Kardashian. Her father was of Armenian descent and her mother is of mostly English ancestry. In 1991, when she was age 12, her parents divorced and she spent her time between their separate houses in Beverly Hills. Her mother married Caitlyn Jenner, 1976 Olympic Gold Metal Champion for the Decathlon and later had two children with him, Kendall Jenner and Kylie Jenner. After the O.J. Simpson murder trial propelled Kourtney's father, Bob, into the spotlight (he was a member of the "Dream Team" of lawyers defending the accused murderer in what journalists hail the "Trial of the Century"), her mother decided it would be safer to move her family to Hidden Hills, California.详情
