Tickets for the Spice Girls reunion tour are going like hotcakes! The tickets for their December 15 concert at London's O2 arena sold out in 38 seconds and are already showing up on eBay for up to 900 pounds ($1,800)! More than one million people in the U.K. registered for the concert. "It was a dramatic moment," said Ticketmaster boss Chris Edmonds. "The sales went live and there was a huge surge as fans bombarded the lines." Three more dates have been added to the tour, which kicks off in Canada on December 2 before going around the world. The fans have definitely told the group what they want, what they really, really want - more Spice!
