The new stage show, which was written by Jennifer Saunders and produced by Judy Craymer (Mamma Mia!), was officially launched in London earlier today (June 26).
Geri Halliwell, Emma Bunton, Melanie C, Melanie B and Victoria Beckham arrived at the St. Pancras Renaissance London Hotel for the announcement.
Since the launch, ticket searches on viagogo UK have increased by 187%, making the musical an initial box office hit.
Based on demand, Viva Forever! is currently proving ten times more popular than Jesus Christ Superstar, which stars real-life Spice Girl Melanie C.
The stage show is also generating double the interest of Nicki Minaj's newly-announced UK arena tour, which goes on sale this Friday (June 29).
All five members of the Spice Girls have been involved in creating the new musical, which will open at the Piccadilly Theatre in London to the general public on November 27.
Tickets for Viva Forever! start at £20 and are on sale now.
