Fashion icon Victoria has decided not to join the tour, but has wished her former bandmates "so much love and fun".
The girls, in an exclusive with The Sun, will be sharing more details about their UK Tour later today, Monday, November 5.
Then, to prove they've all still got it - as if they ever even lost it - they sang a few bars of Spice Up Your Life, before announcing the tour dates.
As for how the Spice Girls will manage without Beckham, that remains unclear. I can't wait to perform to our forever supporting fans and a whole new spice generation! We are going on tour, people need to see it to believe it'. Actress Olivia Munn suggested on The Late Late Show in September that a different celebrity could fill in for Posh Spice every night while on tour.
It's been well over 20 years since the 90s girl band released the single "Wannabe" and left many of us arguing over whether we were Sporty, Baby, Ginger, Scary or Posh. "Hold tight it's gonna be fun".
'Er, Geri?' said a disgusted-looking Mel B as she glanced judgmentally at the star, before adding: 'What is that?'
The social media clip also confirmed that Jess Glynne will join the Spice Girls as a "very special guest".
It is not known why Victoria Beckham will not be joining the reunion tour. "She's just not committing just yet".
Since that time, they have been frequently reassuring fans that a reunion is happening.
Previously, Mel B had teased a tour.
