After much speculation and rumour the Spice Girls announced their reunion tour and Greatest Hits album to the world's media this summer. Fifty five million records sold, an astonishing 9 UK no. 1 singles, three back-to-back Christmas no. 1 singles and with 'Wannabe' the biggest selling single ever by an all female group, the Spice Girls have very little to prove. The band are never out of the media spotlight, the British tabloids and women's magazines adore them and the British public can't get enough. 3.5 million people worldwide have registered for tour tickets, 1 million of those were from the UK.
