The reigning queen of pop paid her respects to the late King of Pop Saturday night with a musical tribute to the star.
Madonna performed in the O2 in London, the same arena where Michael Jackson was set to stage his "This is it" tour on July 13.
As Madonna sang "Holiday" during her "Sticky and Sweet" tour, a Michael Jackson impersonator took the stage, sporting a sequin-embellished jacket, a Jackson-esque white glove, white socks and a white t-shirt. An image of Jackson as a child appeared in the background.
The impersonator then danced to Jackson's "Wanna Be Starting Something" and even took on the music legend's iconic moonwalk.
After Madonna shouted "Let's give it up for one of the greatest artists the world has ever known," the pop star and her dancers wore jeweled gloves on their right hands to honor Jackson in their last dance.
Madonna wasn't the only mega-star that paid tribute to Jackson since his death. U2 gave respects to the musical prodigy at their opening concert in Barcelona when they sang "Angel of Harlem". Bono threw in some lyrics to some of Jackson's greatest hits.
