Katherine Jackson was reportedly 'completely unaware' that her grandchildren were so disturbed by her absence.

The 82-year-old matriarch was reported missing last weekend after Paris claimed she hadn't spoken to her for a week. Katherine has since lost custody of her grandchildren Paris, Prince and Blanket, with the children's cousin TJ Jackson taking over as their legal guardian.

Katherine has now arrived back at the family home in Calabasas, California, after nearly two weeks in Arizona to find her kin in a state of distress.

'It was an extremely emotional reunion with Katherine and the grandchildren last night,' a source told Radar Online.

'Katherine was completely unaware that they had been trying to call her. Katherine heard a much different story about the past week than what she was told by her children, Randy, Jermaine and Janet who were with her in Tucson. Blanket was especially traumatised by Katherine leaving because he is extremely close to her and was absolutely lost without her.

'The kids were all united in telling Katherine that she could never go that long again without contacting them as they had grown so worried about her. Blanket was just glued to her side the entire night and was exhausted with emotion.'
