They last reunited for a hugely successful UK and Irish tour in 2019, which saw them play Croke Park and a series of venues across the Irish Sea.
However, the Spice Girls' reunion was cut prematurely short due to the small matter of a pandemic the following year.
Now, however, it looks like another reunion may be in store if the huge hint dropped by Mel B aka Scary Spice is anything to go by.
The Leeds native, who had previously revealed that the girl group would 'definitely be doing something' to mark the 30th anniversary of their first audition, posted an image of a mural of the iconic girl group at Wembley Stadium, with the caption "Wembley?? I’ll say no more."
The post already has some celebrity fans in a tizzy, including model and actress Cara Delevingne, who replied: "Please!!! I beg you!! I will literally do anything!!"
Other fans have speculated that Mel B's decision to include the neighbouring image of Harry Styles beside the four-piece, which doesn't include Victoria Beckham, holds some significance - i.e. that he will support them on any potential Wembley gig, or perhaps even take Posh Spice's place in the band.
For now, we'll just have to wait and see what's in store...
