The group will reunite for 13-date UK tour next year, culminating with three nights at Wembley Stadium.
Victoria Beckham will not be performing with her former bandmates. Instead it will be left to Mel B, plus Geri Horner, Emma Bunton and Melanie Chisholm to take to the stage.
Music mogul Simon Fuller is masterminding the comeback, and it stands to net the girls around £12million each should the tour be a sell-out.
The Last time the girls were together on stage was the 2012 Olympic Games in London.
