(Cover) - EN Showbiz - Paris Jackson has tweeted her relief at her grandmother returning home.

Katherine Jackson, 82, has been at the centre of a series of family dramas over the past week. The 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. Paris took to her Twitter page to let followers know her grandmother was safe and well.

"grandma's here ! #thankyougod <33 (sic)," she wrote on the social networking site.

Paris, 14, also revealed she'd been losing sleep over the mystery of Katherine's recent whereabouts.

"5 hours of sleep last night , been awake for 23 haha goodnight everybody<33," she wrote, before adding: " time to #hibernate (sic)."

Katherine's return to Los Angeles is the latest development in the Jackson family crisis surrounding Michael Jackson's will and the welfare of his three children.

Earlier this week, police were called to the home where the children live. It's been claimed Michael's siblings Janet, Jermaine and Randy stormed the property, with Janet accused of shouting at Paris. (C) Cover Media
