Victoria cryptically teased in her caption: "Love my girls!!! So many kisses!!! X Exciting x #friendshipneverends #girlpower."
Just weeks later it was claimed that the Spice Girls would voice the characters in an animated superhero movie.
Variety claimed in March 2018 that a film was being shopped to potential production partners with the five stars signing off their likenesses being used in characters.
A source told the publication: "It will feature a girl power message unique to that group member that reflects each girl's personality."
They added: "The Spice Girls are thinking big in terms of a franchise on a global scale. They're the most successful girl group on the planet. It's just what Marvel or Disney needs."
The Spice Girls are no strangers to the film industry, famously starring in cult hit, Spice World in 1997.
Victoria's involvement in the animated movie will come as a shock to fans after she turned down the Spice Girls' 13-show tour.
Mel B, Emma, Mel C and Geri have been touring England, Scotland, Wales and Ireland with their 2019 Spice World tour.
Mum-of-four Victoria revealed late last year that she would not be joining the comeback tour, with the fashion designer said to have had other work commitments.
Sharing the news on Twitter, she wrote: "Being in the Spice Girls was a hugely important part of my life and I wish my girls so much love and fun as they go back on tour, I know they will put on an amazing show and the fantastic fans past and present are going to have a wonderful time!"
