They caused fan hysteria on Friday when they reunited for social media snap, as well as teasing "exciting projects" coming down the pipeline.
And according to the Daily Mail, Geri Horner is keen for the Spice Girls first reunion performance to be at the Royal Wedding of Prince Harry and Meghan Markle.
A source told The Sun that Geri, 45, is keen for the gig to take place since Meghan, 36, was a huge fan of the 90s band.
The source said: "Geri suggested the Royal Wedding is a fantastic opportunity, and that they should offer to perform at the reception.

"And the wedding fits in perfectly with Geri's idea that the reunion should be very British. She sees it as a big part of their identity, and one they should keep."
The source added that so far the Spice Girls have no agreed on the shape their reunion will take, and whether it will involve such a performance.

"The time now feels right to explore some incredible new opportunities together. We all agree that there are many exciting possibilities that will once again embrace the original essence of The Spice Girls, while reinforcing our message of female empowerment for future generations."
The reunion was expected to earn each of the girls $19 million, with ideas such as a TV special, album and endorsement deals all being discussed.
Prince Harry and Meghan, who announced their engagement in November, are set to tie the knot in Windsor on 19 May, and so far it has not been revealed how the ceremony, or the reception, will take shape.
