The Spice Girls may reunite to play at King Charlesâ blockbuster coronation concert in early May, according to a report in the Sun. If so, it would be the first time the band has reunited as a full five-member group since performing at the closing ceremony of the 2012 London Olympics. An âinsiderâ told the Sun: âRoyal organizers are super keen to secure Britainâs biggest girl band, and the Spice Girls are seriously pondering a return to the stage as a five piece for such a historical event. Certainly, the reality is that the Coronation is as special as the Olympicsâa one-off celebration and unique performance. There is a general sense that a reunion could happen for something this significant. Mel B and Mel C are the ring leaders in the group, trying to make it happen.â Mel B recently said the band would reunite for a special occasion. âI canât tell you exactly, but thereâs going to be something that is going to be announced pretty soon.â Geri Halliwell and Mel B famously kissed Charles at an event to mark the 21st anniversary of his Princeâs Trust charity in 1997.
