Rachel Stevens, Tina Barrett, Paul Cattermole, Jo O'Meara, Hannah Spearritt, Bradley McIntosh, and Jon Lee are all said to be in talks to reform following a 12-year hiatus.
And now it appears the reunion will DEFINITELY be happening!
This weekend, the pop band set up a Twitter account, which has since been given the official verification blue tick. Exciting!
Although the band members have not sent a single tweet, they already have more than 4,000 followers.
Rumour has it, S Club 7 are planning their big comeback for this year's Children In Need, which takes place on 14 November.
In August, Paul added fuel to the S Club 7 fire by tweeting: "Big thanks to everyone for your support with the S Club reunion."
Meanwhile, Bradley made his return to the stage on Saturday night when he performed alongside Blue at the 'Big Reunion Boy Band Tour'. Bradley stepped in for Simon Webbe, who was busy strutting his stuff on Strictly Come Dancing.
