MADONNA secured her title as Queen of Pop by entering the stage on a throne for the first night of her world tour.

For a woman who has just turned 50, Madonna could be forgiven for being obsessed with time.

Hello, boyos: Madonna kicks off the first leg of her world tour
The undisputed Queen of Pop has kicked off her latest world tour with a dazzling and extremely athletic performance in Cardiff.

It should come as no surprise that the queen of pop is again courting controversy. The first show of Madonna’s world tour made a foray into U.S. politics with a none-too-subtle dig at U.S. presidential hopeful John McCain Saturday night.

Even at 50, the queen of pop just can’t stop courting controversy.

Madonna started her latest tour last night, a week after turning 50, offering 40,000 fans in Wales two hours of her trademark high-energy disco, costume changes and controversy.

Hours before Madonna launched her “Sticky & Sweet” world tour in Cardiff last night, the phenomenal pulling power of history’s biggest female pop star was evident for miles around.

Fenomenaal en van wereldklasse, zo jubelen de Britse media na de première van Madonna’s wereldtournee.
