Each band member is said to have received £10m to promote a new greatest hits album, along with other still-to-be-announced endorsements. The four band members - Melanie Brown, Emma Bunton, Geri Halliwell and Melanie Chisholm - haven't toured together in nearly a decade and haven't performed together in years. In a mock news bulletin style video, the band announced their upcoming tour dates and that tickets will go on sale this Saturday at 10.30am.
Emma said: "It's time to spice things up all over again!" I can't wait to perform to our forever supporting fans and a whole new spice generation!
"I've said it sooo many times I'm beside myself it's actually happening yipppeeee".
Halliwell tweeted, "I'm sorry about that...everything works out in the end, that's what my mum says!" "Hold tight it's gonna be fun".
Mel B also hopes so too, as she admitted the door will always be open for the mum-of-four.

Rumours of a Spice Girls reunion have rumbled in recent days, ahead of a scheduled appearance on The Jonathan Ross Show this Saturday.
The "Spice Up Your Life" hitmakers confirmed four of the group will be reuniting for six concerts in the United Kingdom next summer in a spoof news bulletin they shared on Twitter.
Back in February, Mel B appeared on the daytime talk show "The Real" and sparked speculation that the group would be performing at Prince Harry and Meghan Markle's wedding.
In the summer, it was claimed that she was unable to pay her back taxes, with her and Stephen owing hundreds of thousands of dollars dating back to 2016.
