The 19-year-old aspiring actress is said to be upset with her late father Michael Jackson's sister Rebbie, as Paris feels she is trying to stop the "Thriller" hitmaker's brood - also including 20-year-old Prince - from seeing their grandmother Katherine Jackson, TMZ reported.
The 86-year-old matriarch is staying at Rebbie's leaving Blanket practically alone at his grandparent's Calabasas property.
Katherine has been away from her home for months having been in London for two months in January before returning to Los Angeles.
This has sparked concern in Paris as Michael's choice of guardians in Katherine and 38-year-old cousin Tito Jackson are not looking after Blanket.
