Fans never thought they would see the Spice Girls perform together again after the most successful ever girl group called it a day.
But "girl power" reigned over the Olympic Stadium as the quintet reformed once more.
Geri Halliwell, Emma Bunton, Victoria Beckham, Mel Chisholm and Mel Brown emerged out of five black cabs, fashioned to the style of each singer.
One cab was baby pink, one had sporty stripes, another had posh diamante the next was adorned as the union flag - reminiscent of Halliwell's famous Brit awards attire - and the final cab was covered in animal print.
The band performed their debut single Wannabe before they paraded around the arena on top of the cabs while singing Spice Up Your Life.
