Meanwhile, Kardashian's fiance Kanye West is reportedly installing a panic room in the couple's Los Angeles mansion. The room will provide a hiding place for the family and will be equipped with cameras and a high-tech alarm system to notify police offers in case of an emergency, according to The Sun.
