London, Mar 6: Details of Michael Jackson’s comeback gigs were leaked even before the official announcement when blundering advertisers put up posters plugging the shows hours.

While the organisers of the gigs at London''s O2 Arena tried hard to keep the details under wraps, London Underground tube network was emblazoned with ads confirming the tour.

The ads revealed that the Thriller hitmaker would play a total of ten shows at the O2 in July (09).

The billboard shows Jacko dancing with one hand in the air, with the slogan: "This Is It - 10 Shows, July ''09, The O2 Arena."

"The organisers were told earlier today that the posters have already gone up on the tube,” the Daily Express quoted a source as saying.

“They are furious - this wasn''t meant to happen," the source added. (ANI)
