Emma Bunton has promised that the forthcoming musical inspired by the Spice Girls' songs will be "amazing".
The mother of two said she couldn't wait to see the show which is expected to open next year.
She said: "It's going to be amazing. I've heard a little bit about the story but it's top secret".
Absolutely Fabulous star Jennifer Saunders is writing the story for the musical, which is called Viva Forever.
Emma – known for many years as Baby Spice – said all five members of the group have stayed in touch since the group's split.
"Now we've all had children there is so much for us to chat about and we keep in touch with emails," she added
