The Spice Girls reunion tour is reportedly in crisis because Mel C won't agree to it without Victoria Beckham.
While fashion designer Victoria says she is too busy with her fashion label to reunite with her former bandmates, Mel reportedly told the other three members - Mel B, Geri Horner and Emma Bunton - that she will only take part if all elements are in place.
A source told The Sun newspaper: "This means good management, good tour promoters and good sponsorship to maximise revenue. To fulfil this Mel believes the band has to be the original five-piece and Victoria needs to be involved."
Mel B previously admitted the group are keen to "make sure something happens" for their 20th anniversary next year but nothing is set in stone yet.
Asked about the chance of a reunion, she said: "Potentially, yeah. Once we sort everything out we make an announcement, but right now we're just figuring it all out. Next year is your 20 anniversary so we're really just trying to make sure something happens.
"We're figuring stuff out. As soon as we figure it out we'll tell every detail, but until then there's not much to say. It's like when you're dating somebody and everyone is forcing you to get married. It's like, 'We're getting married! Just give us a second to figure it out!'"
