The limited edition vinyl and cassette, titled Wannabe25, will be available to stream from July 9, with physical copies out for release two weeks later.
It will include the original single, a remix by Junior Vasquez, the original demo recording, and ‘Feed Your Love', a demo of a previously unreleased ballad.
Wannabe, originally released on July 9, 1996, became on of the girl group’s most well-known hits and has since broken numerous records.
It is the seventh best-selling debut single of all time, with over 1.3 million CD singles and download sales, as well as the longest-reigning number one by a girl group.
The EP release comes alongside a social media campaign #IAMASPICEGIRL, which encourages fans of the group to send in their memories and stories to be shared on the Spice Girls social media.
The exciting news for fans comes just days after Victoria Beckham revealed a new round of Spice Girl merchandise to support the LGBTQ+ community and celebrate Pride Month.
The former Spice Girl cleverly played off the name off of Wannabe for the iconic girl band’s offering, a charity t-shirt and purse, emblazoned with the words ‘Proud and Wannabe your lover’.
She said all profits from the tee will go to Albert Kennedy Trust to fund the “amazing” work they do to combat LGBQT+ youth homelessness in the UK.
Posting a picture on Instagram with all five original members wearing the T-shirt, Beckham wrote: “Pride to me is a celebration of being completely yourself and this year’s T-shirt is a reminder of that.
“The Spice Girls really championed accepting yourself and others, being kind, having fun and just living your best life.”
