Madonna 'booed at London concert'

Madonna was reportedly booed by her fans after arriving late to her London 'Sticky & Sweet' live show on Saturday.

The '4 Minutes' singer kept the audience waiting for one hour in "sweltering conditions" at the capital's O2 arena, according to Metro.

Eventually appearing on stage in a mock-up white Rolls Royce, she said: "All right London, get up."

During her set, the star paid tribute to Michael Jackson in a segment which included one dancer moonwalking across the stage as well as video clips of his hit songs 'Billie Jean' and 'Wanna Be Startin' Something'.
