She's back once again, Madonna....She will be doing a world tour in selected countries promoting her songs and her album. After the word drop against Lady Gaga, Madonna is showing the world that she is still around and nobody can take her post as the queen of pop. Michael Jackson was the king of pop and he is already dead. Madonna's world tour only prove one thing, that she is still hot and Lady Gaga should be cautious in every thing that she does.
