The band have now pulled plans to take their reunion tour to Australia, China, South Africa and Argentina - and will play their final gig in Canada later this month.
Mel C had been locked in talks with bandmates VICTORIA BECKHAM, GERI HALLIWELL, EMMA BUNTON and MEL B over the band’s future.
But Sporty Spice does not want to continue so the girls have decided to call it a day.
Last night a Spice source revealed: “Geri and Victoria have been loving the attention and adulation the tour has been bringing the girls in the UK and North America.
“Mel B has really enjoyed being on stage and performing again. And Emma has found it hard with a young son but was prepared to carried on.
“But Mel C is the one who always insisted the reunion should be only short-term. Now she wants to go back to doing her own thing.
“Because they couldn’t all agree the extra tour dates have been pulled. Touring has been harder on all the girls this time round. But all of them could have been persuaded to continue - apart from Mel C.”
The band yesterday announced their gig in Toronto on February 26 will be their last.
Their statement added: “Sadly the tour needs to come to an end by the end of February due to family and personal commitments for Emma, Geri, Mel B, Mel C and Victoria.
“It was announced in June that, as well as the Europe and North America dates, the girls planned to visit Australia, China, South Africa and Argentina.
"But due to the phenomenal demand for tickets in the UK and US, and the tour’s massive logistics, it was impossible to fit in everything.”
The Return Of The Spice Girls tour kicked off in Vancouver, Canada, on December 2 last year. It was the first time they had appeared as a five-piece since Geri left the band in 1998.
Dates were set for concerts in Cape Town, Buenos Aires, Beijing and Sydney this month.
But the tour schedule changed due to demand for extra London gigs and new dates were never set.
There were also questions about whether the girls could sell out all the cities.
The band said yesterday: “It’s been incredible being back together and seeing our fans again. Really sorry if we didn’t get to see you this time round.
“We have other commitments in our lives now. But who knows what will happen next?”
The band are making the most of their remaining tour time - Mel B celebrated a sell-out gig in Montreal, Canada, by DJ-ing at a local club.
But I think this is the last Spice world tour we will see - although I wouldn’t rule out another money-spinning stint in London or Las Vegas.[source]
