"This time next year at least four of the five girls will be back on stage doing the Spice material again," The Sun quoted a source as saying.
"Both the Mels and Geri are the driving force behind making it happen. They have agreed to meet up again next week and thrash out their plans for the future of the Spice empire.
"Emma is being cautious but the minute she's with the girls they'll talk her round. When Geri left the first time, she was arguably the band's biggest star. If they coped without her, they are confident they can make it work without Posh," the source added.
