Madonna will pay tribute to her late friend, Michael Jackson, at her Saturday concert at London's O2 arena, on the very same stage Jackson was to kick off his comeback tour this summer.

The singer's rep, Liz Rosenberg, confirms the Material Girl will debut a special song and dance to honor Jackson. On Friday, rehearsal photos were posted online of the tribute sequence, which features Madonna flanked by a Jackson lookalike wearing his signature white glove.

Saturday's show marks the first of two Madonna will stage at the same London arena where Jackson was set to make his concert comeback July 13.

In the days following Jackson's June 25 death, Madonna fondly remembered her friend.

"I can't stop crying over the sad news," Madonna, who was escorted to the 1991 Oscars by Jackson, said in a statement to Access Hollywood. "The world has lost one of the greats, but his music will live on forever! My heart goes out to his three children and other members of his family...God bless."
