“We hope everyone can join us for one big Spice Girls party!” a statement from the group said.
Shortly after the announcement, Glynne tweeted: “ARE YOU MAD! I'm Joining @spicegirls ON TOUR! Y'all best come through cause this stadium tour is gonna kick OFF!”
The group had last performed together during the London Olympics closing ceremony in 2012, and last toured together ten years ago.
Tickets go on sale at 10:30am on Saturday, 10 November 2018.
