Madonna

Crowned "The Greatest Woman in Music" by VH1 this year, the queen of pop ascends her throne for a series of local megagigs in support of the recent MDNA LP. Madonna has run into a spot of bother on this world tour—French right-wing party the National Front tried to sue the singer for showing its leader with a swastika on her face, and antigay activists in Russia took issue with Madge for criticizing a recent law. But after her nearly 30 years in the biz, we know it's just fuel to Madonna's fire (join the queue, behind the Vatican), whose Super Bowl half-time show was the most watched performance in the game's history, drawing 114 million viewers—more than the actual game.
