The Queen of Pop honors the King of Pop

Madonna revived last year's record breaking Sticky and Sweet Tour last week at London's O2 arena just nine days before Michael Jackson was set to play 50 shows in the same venue. The Queen of Pop took the chance to honor the late King of Pop by playing "Billie Jean" halfway through her hit "Holiday" as one of her dancers, Kento, impersonated Jackson.

"He was obsessed with Michael all his life," Madonna said. "And when Michael was having auditions for his tour, Kento really wanted to go but he'd already made a commitment to me. So now he's about to have his moment and be Michael at my show."

Madonna also revealed that she had planned to perform with Jackson at one of his upcoming concerts. At one point in the concert the singer wore a black armband and a single white glove while lyrics to Jackson's "Man in the Mirror" flashed on screens above the crowd.

The Sticky and Sweet Tour continues its run in Europe throughout the summer as Madonna prepares to launch a new two-disc greatest hits collection, Celebration, including several new songs produced by DJ legend Paul Oakenfold. The first single from the collection, "Celebrate," is rumored to be a return to the singer's '80s dance sound and will be released on July 28 (though rumors say the premiere of the single might happen as soon as today).
