Former Blazin' Squad star Kenzie, Gareth Gates, Dane Bowers, Kavana and Adam Rickitt have spent the afternoon in the studio together and shared their first group snap.
All the lads' are wearing uniform jeans and black tops in the photo, which they uploaded to Twitter via their new official 5th Story account.
Alongside it, the boys wrote: "Here we go! It's 2014, @BigReunionITV is just around the corner & the work has really begun. We are #5thStory."
Gareth also teased fans by posting a snap of an empty dance studio complete with five microphones on stands.
"5th Story set to go!" he told his followers.
Following the success of last year's Big Reunion, Kenzie, Gareth, Dane, Kavana and Adam are set to grace our screens in the second series as super-group 5th Story.
The Big Reunion kicks off on ITV2 next month, and the lineup also includes 3T, Girl Thing, Eternal and A1.
