A list of Michael Jackson's bizarre backstage demands has been revealed ahead of his summer tour.

The Mirror reveals that the star has thrown his comeback tour into chaos with his unreasonable diva demands.

On the list of things Jacko must have are a racially diverse mix of choir children (who can all do sign language) and a selection of drummers (none of whom can have a beard).

Jackson's weird request has been sent to casting agents ahead of the King of Pop's 50-date residency at London's O2, which starts in July.

While the superstar wants every child on the tour to be able to communicate in sign language, he also insists the child singers must be made up of "exactly equal" numbers of black, white, mixed-race and Asian kids.

But perhaps most bizarrely, Jacko is also recruiting for six beardless drummers.

The email seen by The Mirror clearly states the freshly shaven musicians must be "young adults, clean-cut and of mixed ethnicity."

A source close to Jacko's tour promoters told The Mirror his demands were a "logistical nightmare".
