Girl power is back. While Irish group Westlife members decided to go on their separate ways, British pop sensation Spice Girls reunite to announce the details of a musical to be launched in London.

The said musical is based on their hit songs and the storyline is based on their fame and the tale of a female friendship. For the first time, the girl group reunited after four years since their 2007-2008 reunion tour. Geri Halliwell, also known as "Ginger Spice," famously left the group with bitterness in 1998 and then the group eventually split up.

The five members of the Spice Girls have not appeared publicly together until now. These girls are very excited for the upcoming new musical which will be based on their experiences while featuring their biggest hit songs.

Numerous speculations about the musical show and the non-stopping conflicts between the Spice Girls members have been circulating for months. However, the famous members of the group namely Victoria Beckham, Geri Halliwell, Emma Bunton, Melanie Chisholm and Melanie Brown made a public appearance showing their support for the musical launch.

According to The Associated Press reports, the "Viva Forever" musical revives the music of the girl powered group in the 90s. It simply tells a story of four good friends whose closeness with one another is put to the test when they become a part of a television talent show. The Spice Girls admitted that they were really delighted with the upcoming show. "Viva Forever" will be produced by Judy Craymer and she is none other than the woman behind the success of the ABBA musical film "Mamma Mia."

"It's better than we could ever have imagined," said Melanie Chisholm, also known as "Sporty Spice." The musical show is written by comedienne Jennifer Saunders, who co-created the TV sitcom "Absolutely Fabulous."

Meanwhile, Victoria Beckham said that the show would totally introduce a new meaning to Girl Power. "Viva Forever" will have its preview this November and the musical will finally have its grand opening at London's Piccadilly Theater in December.
