Madonna Triumphs at the Launch of ‘The Celebration Tour’ in London

Madonna reminded in earnest why she is the Queen of Pop at the electrifying launch of ‘The Celebration World Tour.’

The slick production set sail at London’s O2 Arena and served as the first of six sold-out shows at the iconic venue.

Already one of the year’s most eagerly awaited spectacles, the global trek was dramatically postponed early this summer after the singer battled sudden health issues.
