The Spice Girls have reunited in London to launch their own musical, revealing they cried when they saw some of the songs being performed.

Viva Forever debuts at the Piccadilly Theatre in the West End in December and will feature songs from the band's back catalogue.

Jennifer Saunders is behind the script, while Judy Craymer, the lady behind Mamma Mia, has produced the show.

"When we watch the workshops, each time the songs started we got goosebumps, it just brings back so many memories," said Melanie C.

Victoria Beckham revealed seeing Mama performed would be the most emotional.

She said: "We've all got children and being mums is all of our priorities."

Viva Forever charts the tale of a young girl and how overnight fame impacts her relationship with her mum and best friends.
