Katherine Jackson – mother of Michael and Janet Jackson – has been reported missing, according to the L.A. County Sheriff’s Department.
According to a report filed by her nephew Trent late Saturday night, Jackson had not been heard from in a week. Paris Jackson confirmed the report via Twitter, writing: “yes, my grandmother is missing. i haven’t spoken with her in a week i want her home now.”
But her son, Jermaine Jackson, seemed to deny the missing person report, Tweeting Friday: “I want to reassure everyone (inc all sudden medical experts) that Mother is fine but is resting up in AZ on the order of a doctor, not us.”
