With all the news of Michael Jackson, we almost forgot that Madonna's Sticky & Sweet tour was rolling into town this weekend. Madge took to the stage Saturday night at London's O2 arena, the same venue where Jackson was due to kick off his comeback tour this summer. Unable to attend his memorial this Wednesday, Madge paid tribute to the King of Pop with a lookalike Jackson dancing to a medley of his songs (watch a video after the cut).

She also unveiled a specially-designed couture Givenchy outfit, created for her by Riccardo Tisci. Her look comprised of a black cropped jacket embroidered with black jet stone, fringe, lace and organza, and an waistcoat with jet encrusted straps.
