The tour will be comprised of 11 different cities, including a gig at the 3Arena in Dublin on the 16th of October 2023.
"After eight years it feels amazing to announce that we're reuniting and performing together again,” the group said.
"We're so excited to bring the S Club Party back to our fans across the country to celebrate 25 years of S Club 7.
"We can't even believe it's been so long! Music and friendship have always been at the core of everything that we've ever done.
"We hope everyone can join us for one big party!” they added.
“We can’t wait to be reunited with you all this October,” the group wrote on their social media channels.
