Madonna paid special tribute to Michael Jackson when she resumed her Sticky & Sweet tour in London Saturday night.

Madonna performed a special song and dance number in memory of Michael, according to the Associated Press. First, a photo of a young Michael was shown on stage, while Madonna performed "Holiday." This was followed by the entrance of an MJ impersonator, dressed in homage to the late King of Pop.

The concert took place at London's O2 arena, where Michael was slated to stage his 50-date tour.
