A musical based on the career of multi million-selling U.K. girl group The Spice Girls has been green-lighted by the act's manager, entertainment impresario Simon Fuller.

Fuller, who developed reality TV giant "Pop Idol" and subsequent variants such as "American Idol" after overseeing the Spice Girls' global success, has struck a deal to develop the musical with Judy Craymer, producer of the global film and theatre hit, "Mamma Mia!" The musical has the working title of "Viva Forever" -- a U.K. No. 1 for the band in 1998.

The show is being created by Judy Craymer Productions, a newly-created joint venture between the producer and Universal Music U.K., set up specifically to stage musical productions. The production was given the go-ahead after Craymer struck an agreement with Fuller's new global entertainment company XIX Entertainment and the members of the band.

Describing himself and the band members as "very excited" to be working with Craymer, Fuller added in a statement: "What Judy has achieved with her all conquering box office smash hit 'Mamma Mia!' and what the Spice Girls created with their powerful record breaking mix of 'Girl Power!' and hit songs, has influenced Pop culture more than anyone can imagine."

"Now, with this incredible new project "Viva Forever" we all come together as partners with a combined focus to create something really special for this next decade," he continued.

Fuller will act as executive producer on the show. No information regarding when or where it will be staged has been released, although a spokesperson for Judy Craymer Productions tells Billboard.biz that it is not likely to open for approx "2 to 3 years."

"I'm delighted that Simon Fuller and The Spice Girls are so supportive of the idea of Viva Forever," said Craymer in a statement. "I want to create a unique celebration of the band and its music, with its own flavor and joyful message. It is important to me that the excitement, style and humor of The Spice Girls is well represented on stage."
