The Spice Girls reunited for a world tour in 2007. The reunion was announced on 28 June 2007, when all five original members—Melanie Brown, Emma Bunton, Melanie Chisholm, Geri Halliwell and Victoria Beckham—appeared together at London’s O2 Arena.
The tour, officially called The Return of the Spice Girls Tour, began in Vancouver on 2 December 2007. It marked the group’s first major performance together as a five-member lineup since Geri Halliwell left in 1998. The concerts featured the group’s biggest hits, including “Wannabe,” “Spice Up Your Life” and “Viva Forever,” alongside material connected with their Greatest Hits release.
The tour continued into 2008, which explains a common source of confusion: it is often described as a 2007–2008 tour. However, the reunion announcement and the tour’s launch occurred in 2007, making that the canonical answer to this question. The Spice Girls later reunited for the 2012 London Olympics closing ceremony and toured again in 2019, but neither event was the reunion world tour referenced here.
