Kris Jenner is on the warpath, trying to find the culprit of what police believe to be a prank call to L.A County's Department of Children and Family Services. TMZ reports that on Friday, someone called to report that Kendall and Kylie Jenner were in danger. Social workers and police visited the house and soon learned that the girls were A-OK, despite having Kris Jenner for a mom. A rep for the family said the allegations were "ridiculous" and probably stemmed from a tabloid reporter. "It's such a shame that anyone can make up such hurtful and hideous untruths especially when children are involved," the rep told TMZ. "We are taking this matter very seriously and investigating to find out who is responsible for fabricating such a terrible story and will take the necessary legal action so that this does not happen again." Kris Jenner reportedly has hired a private investigator to figure out who called in the krazy klaims.
