Kris was born in San Diego, California, on November 5, 1955, to Mary 'MJ' Campbell—a children's clothing store owner—and engineer Robert "Bob" Houghton. When she was seven years old, M. J. and Bob divorced, and Kris and her younger sister, Karen Casey, were raised by their mother, who often appears on the Kardashian reality shows. She later married businessman Harry Shannon, who helped raise the two girls.
