Washington, July 1 Michael Jackson's 12-year-old son Michael Joseph Jackson, Jr. also known as 'Prince' was set to make his stage debut with his father during the tour, it has emerged.

The singer's long-time family confidante and biographer Stacy Brown has claimed that the King of Pop was busy working behind-the-scenes with Prince who was going to both sing and dance on-stage, reports Fox News.

However, concert promoters AEG said that they had "no knowledge" that this was going to happen.

Meanwhile, Dieter Wiesner, who managed the singer, has claimed that Jackson plunged deeper into drug addiction when child sex abuse allegations piled up.

Jackson once got so doped up that he could not lift a fork to his mouth at dinner, according to Wiesner. (ANI)
