There are rumblings that the Spice Girls may attempt to put their differences aside long enough to perform at a special concert to celebrate Nelson Mandela's 90th birthday.

The girls announced last week they will be cutting short their reunion tour, amid persistant rumours of in-fighting and jealous rivalries.

But this hasn’t stopped organisers of what is being billed as the ‘Concert of the Decade’ from trying to woo the group back on stage.

A source tells The Mirror: "Nelson is desperate for them to perform one last time - and he's confident it will happen.

"He first met the Spices in 1997 and called them his 'heroes', so he has deep admiration for them."

Other names keen to perform at the June concert in Hyde Park include Robbie Williams, Bono, Rihanna and Jay-Z.
