Madonna Pays Tribute to Michael Jackson in Concert

Cameron Diaz paid tribute to Madonna on the cover of V Magazine.

On July 4, the reigning queen of pop paid tribute to the late King of Pop, Michael Jackson, with a musical tribute to the star at the O2 arena in London.

In the same arena where Jackson, who died of cardiac arrest June 25, was set to stage his This Is It! series of concerts beginning July 13, Madonna sang "Holiday" while a Jackson impersonator took the stage, sporting a sequin-embellished jacket.

An image of a young Michael Jackson was projected in the background. The impersonator then moonwalked to his hit "Wanna Be Startin' Somethin'."

Madonna said, "Let's give it up for one of the greatest artists the world has ever known." She and her dancers donned jeweled gloves on their right hands to honor MJ for their final dance. Check out the video of Madonna's tribute below ...
