The Spice Up Your Life hitmakers confirmed four of the group - Emma Bunton, Geri Horner, Mel C and Mel B - will be reuniting for six concerts in the United Kingdom next summer in a spoof news bulletin they shared on Twitter.
I won't be joining my girls on stage again but being in the Spice Girls was a hugely important part of my life and I wish them so much love and fun as they go back on tour next year.
Victoria Beckham was absent from the clip.
June dates have been scheduled in Manchester, Coventry, Sunderland, Edinburgh, Bristol and London.
"The girls aren't going on tour", Beckham said during New York Fashion Week.

Scary was joined by a friend dressed as David Beckham, who held a sign saying: "Please, please, please do it for the Spice Girls fans". "There is a reunion tour happening, now it's going to be - I'm not supposed to say when - but it is happening", she said on the United Kingdom show Loose Women.
The Spice Girls previously reformed for a tour in 2007 and 2008 but it was controversially cut short. "I didn't like to say that, but we'll go everywhere else in the world, but right now it's just in the United Kingdom".
The Sun newspaper was first to report that a tour announcement was in the works, suggesting that Beckham would not join the other four.
The group said in a statement: "We are beyond excited to be reuniting next year for a stadium tour!" "It'd be a shame if she didn't".
The official dates and locations will be announced later today, but this reunion has been a long time coming.
Last year Halliwell Horner apologized via Twitter for leaving the world tour in the middle in 1998.
