Jacko 'has only managed two rehearsals'

Michael Jackson has attended just two rehearsals for his forthcoming residency at London's O2 arena, according to a report.

The pop legend is said to be 'in a stupor', leading to fears that the project could be cut back or scrapped altogether.

Jackson has already postponed the opening four nights of his comeback. Concert promoters AEG explained the delay by insisting that organisers needed more time to prepare for the production's "size and scope".

However, a source told the Daily Mail: "The suggestion that they need more time to set up the show in London is a joke."

The insider added: "I think the fans who have already bought tickets should hold their breath and cross their fingers, because there is no guarantee any of this is actually going to happen. There is a possibility that this will still happen, but it is up to him to get his act together.

"Michael has only been to two days of rehearsals for the show. His dancers have been working on it every single day for 45 days at the Shrine Auditorium in Los Angeles, but Michael has been nowhere to be found."

The opening show at The O2 is currently scheduled for July 13.
