Lived with her parents in Colorado, until her parents divorced. Her dad moved to Laguna Beach, California with her brother, and she moved to Illinois with her mother. She also has a stepfather and stepbrother there. She acted out while there to get attention and, after her mother couldn't handle it anymore, Kristin moved to Laguna Beach to be with her dad and brother. Her freshman year, she attended a Catholic school with the uniforms to boot. But that year, she took Driver's Ed at Laguna High.. where she met Alex Murrel (aka Alex M.) and soon the rest of the Laguna Beach: The Real Orange County (2004) crew. She convinced her Dad to let her switch to the public school starting her sophomore year.
