The tour will comprise of five of the original members.
Iconic British pop band, S Club 7 has rebranded to S Club following the death of former band member, Paul Cattermole.
Paul Cattermole was the founder of the band and died at his home in Dorset on April 6 - he was just 46 years old.
Hannah Spearritt will not join the band's 25th anniversary celebrations which means the band will perform as a five-piece.
The number seven was removed from their website and social media over the weekend.
Speaking on his Instagram story yesterday, S Club 7's Jon Lee said: "You’ve probably noticed that there’s only five of us here today, and although Hannah will always be part of S Club 7, she won’t be joining us on this tour.
"It's really really hard to process"
The five of them were reduced to tears but Lee said: "We have been in a bit of shock and it has taken a while for us to find the right words to describe how we feel about losing our brother Paul."
Rachel Stevens said that they are all just taking the time to process Paul's death and want to remember all the good memories they had together.
S Club's Tina Barrett said: "It is just really sad, it is really really hard to process it right now."
Bradley McIntosh also spoke about the devastating news, and said: "All still in so much disbelief, Paul was a big brother to us, all of us and you guys out there. He truly was a unique specimen of human being.
"No one could replace our Paul, he lives on inside in each and every one of us."
The pop group also announced that their 25th anniversary tour will be renamed the 'Good Times' tour in memory of Paul.
"We wish her all the best for the future."
The band members also paid tribute to Paul in their emotional video.
