The only contemporary to rival Michael Jackson in her star power, Madonna is planning to pay tribute to the King of Pop as part of her concert tonight in London. According to the Associated Press, the celebrated singer will use part of the concert to perform a choreographed dance in honor of Jackson and his distinctive moves. The concert will take place at the O2 arena, the same place Jackson was scheduled to perform in his comeback concert series, which was slated to begin July 13.
