The recent wrap-up of their shortlived reunion tour may not be the last we see of the Spice Girls in 2008. The iconic group is being courted for a live performance at Nelson Mandela’s 90th birthday concert at London’s Hyde Park in June.

Organizers Bono and Naomi Campbell want the Spicy Ones to join the A-list of entertainers already expected to take the stage, including Annie Lennox, The Rolling Stones, and Jay-Z and Rihanna.

“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.”

“This concert is going to be the talk of the decade,” adds our insider. “Nelson is a hero and thousands of fans will turn out to support him - as well as the biggest names in showbiz.”
