The Spice Girls have all but confirmed a reunion gig as they celebrated the 20th anniversary of their debut single Wannabe.
Emma Bunton, Geri Horner and Melanie Brown - also known as Baby, Ginger and Scary - shared the same video of them teasing a big announcement on Friday morning and appearing to have dubbed themselves GEM.
"We have the best fans in the whole entire world," says Mel B.
"You've stood by us for twenty years and we want to say a big thank you," adds Geri.
"We've had our ups and downs but you've always been there," chimes in Emma.
"And we want to celebrate and have a party. And when we do, you're all invited," the trio announced in unison.
Hinting at the reunion gig, supposedly planned for July next year in Hyde Park, the video ends, "We hope to tell you soon what you want, what you really, really want."
Missing from the video were Mel C and Victoria Beckham.
While Mel celebrated the band's big birthday with a Twitter post, Posh seemed to have forgotten the anniversary - although she did share the video remake of Wannabe created for the UN's Global Goals earlier this week.
The teaser was received with a lot of excitement.
And fans everywhere were celebrating Wannabe's birthday.
