Emma Bunton, Geri Halliwell, Melanie Brown, Melanie Chisholm and Victoria Beckham — best known as Baby Spice, Ginger Spice, Scary Spice, Sporty Spice and Posh Spice — released their debut single, "Wannabe," in July 1996. 11 years later, in June 2007, all five Spice Girls appeared together in public for the first time since their 2000 split to announce that they would be reuniting for a world tour, greatest-hits album and documentary.

"For us it's about celebrating the past, enjoying each other and it's about our fans. It was kind of now or never," Geri said at the London press conference.
