Declared by MTV the "queen of pop", Miley Cyrus takes the stage shared by legends on MTV Unplugged tonight (airing tomorrow). It has also been said that one of her special guests will be Madonna and she'll duet with her. Is this the passing of the crown? Is Miley now the queen of pop after collaborating with the legendary Britney Spears first and now taking the stage with the legendary Madonna? Is history repeating itself?
