Media tycoon Simon Fuller has revealed he is teaming up with the creator of global hit Mamma Mia! to bring a Spice Girls musical to life.
Judy Craymer, who is thought to be worth €86m from her film and stage hit based on Abba songs, is to create the show, which is tentatively titled Viva Forever.
The Spice Girls musical has been rumoured for months after the band met up to discuss the project, but has only now finally been confirmed.
There will be huge expectations from the show, which is one of the first projects from Fuller's new global entertainment firm XIX.
Mamma Mia! has taken more than £1bn at theatres, and the movie version is the highest-grossing film ever released in Britain.
The Spice Girls became worldwide superstars in the late 1990s, guided by their manager Fuller, with a string of number one hits.
They sold more than 55 million records, packed huge venues and starred in their own movie.
When Geri Halliwell left the band she enjoyed a successful solo career, with Mel B, Mel C, Emma Bunton and Victoria Beckham eventually following suit by releasing records in their own right.
The musical is being billed as a production which will "harness the distinct personality of The Spice Girls to celebrate the energy of the biggest girl-band of all time".
Producers, who stress it is "not a tribute show", expect it to open in London within the next three years.
