The Mirror quoted a source as saying: "It was a meeting of two great musical try minds. Madonna was so impressed with Janet's tribute to Michael that they started talking about how great it would be to honour him by doing something together. With that one performance, Janet proved she's back on top of her game. And who better to join forces with than Madonna? There was definitely something very interesting being planned between them."
According to Madonna"s manager, Guy Oseary, the 51-year-old singer was very eager to be a part of Jackson"s This Is It show at London's O2 Arena. Oseary had revealed this on his Twitter post that said: "A month ago Madonna told me she wanted to do a surprise performance at one of Michael Jackson's UK shows."
