It's been four years since they reunited for their Return Of The Spice Girls tour.
Victoria Beckham, Emma Bunton, Melanie Chisholm, Melanie Brown and Geri Halliwell went back to where it all began - the St Pancras Hotel in London, where they filmed their Wannabe video in 1996.
And following months of speculation whether or not they would join forces again, all five members of the Spice Girls got together in London today to announce details of a West End musical based on their songs.
The musical, titled Viva Forever!, will tell the story of 'a beautiful, talented girl and her best friends who get swept up in the obsession of today's TV celebrity culture'.
Viva Forever! opens at London's Piccadilly Theatre on 11 December.
