Spice Girls
Girl power! Debuting in 1994 with “Wannabe,” the powerhouse group — Mel C, Emma Bunton, Mel B, Victoria Beckham and Geri Halliwell — became the best-selling female group of all-time. Haliwell left the band in 1998, but the five women reunited for a world tour in 2007. The British pop stars also performed during the closing ceremonies at the 2012 Olympics in London.
