The family of the mother of Michael Jackson is pleading for her safe return.
Katherine Jackson hasn't been seen by her grandchildren for almost a week and concern is growing about her well-being.
Michael Jackson's daughter, Paris, tweeted:
Katherine is the legal guardian of Michael Jackson's children. They said she was "in great health physically as well as mentally" when they last saw her.
She said she was going to see her sons' tour in Arizona but never turned up.
