Michael Jackson was so addicted to drugs his staff had to stop him getting high on planes.
Dieter Wiesner, who was Michael's manager from 1996 to 2003, claims the singer was often so "out of control" on prescription medication, he had to be watched at all times to make sure he didn't overdose.
Recalling one harrowing trip, Dieter said: "On one flight Michael sat in the back row with Paris, and I sat in the row in front with Prince.
"I made sure the doctor was in front and I would watch him for the whole flight to make sure he didn't walk back to Michael and slip him something."
