The Spice Girls are back!!! After much speculation and rumour the Spice Girls have announced their reunion tour and the release of their Greatest Hits album. Fifty five million records sold worldwide, 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.
