The five-piece sent the rumour mill into overdrive on Friday after Victoria Beckham, Emma Bunton and Geri Horner all shared a smiley photo of the bandmates back together. "So many kisses! X Exciting x #friendshipneverends #girlpower", so yes, we are SCREAMING with joy and nostalgia.
The newspaper reports that the girls could stand to rake in £10 million ($17.5 million) each from from the reunion.
Speaking about their possible reunion, a source told The Sun: "This is the pop reunion no one thought would ever happen again. The time now feels right to explore some incredible new opportunities together".
This latest reunion news comes after Mel B, 42, hinted she was feeling nostalgic when she posed with clothes from her days as Scary Spice on Instagram earlier this week.
The reunion will allegedly involve a TV talent show, endorsement deals and a compilation album celebrating their greatest hits.More news: USA touts vision for free and prosperous Americas

Tell me what you want, what you really, really want - a Spice Girls reunion!
The Spice Girls have reunited and everyone is properly freaking out. "Even if you've got five really nice people to say you all like the same colour is hard", she said, later clarifying that all the members were "really nice girls".
Unfortunately, for Horner and Beckham, a Spice Girls tour may be impossible to pull through as both members are committed to their respective families and businesses.
It marks the first time the group have been pictured together since 2012.
The Spice Girls have officially reunited after a long six years apart, and we're screaming with excitement.
Speaking on The Nightly Show, she said: "That's where I'm at right now, that's where myself and Victoria are at".
