It’s not yet known whether the reunited Spice Girls – whose website refers to them simply as GEM, after the initials of their first names – intend to perform the songs that made them famous during their reunion tour.

The one-time Spice Girls producer, Eliot Kennedy, reportedly posted two tweets in May indicating that he had been working with Bunton, Brown and Horner again. He has since closed his Twitter account.

“Now that was a day for the history books. Like 20 years never happened. Proper friendship! Hit song!” Kennedy apparently wrote, adding: “Two long but ab-fab days with a stonking hit at the end of it! We’ve still got it kids!! #20years”.

In June, Mel B confirmed that the trio had been working on new music together. “We’ve been in the studio kind of experimenting with some different sounds and stuff like that, but nothing to be able to share just yet,” the former X Factor judge told Access Hollywood Live.
