Washington, June 20 (ANI): A new tell all documentary on the infamous '90s girl group Spice Girls is being planned to coincide with their new musical, 'Viva Forever,' hitting London's West End in December.

With worldwide sales of over 75 million, they defined a generation. But their full story has never been told, Fox News quoted a source as telling the Mirror.

Producers want to spend time getting to know each of the girls and let viewers feel they've got the real insight into their lives, the source said.

Producers, however, are reportedly concerned that the group's biggest star, Victoria Beckham, might be too Posh to take part, in which case the documentary would be called off. (ANI)
