Singer Mel C insists the group - who went their separate ways in 2000 and reformed for a string of concerts in 2007 - are far too busy with their own careers to get back together, despite recent speculation.
She told the Daily Star newspaper: "There`s no chance of that happening. Don`t believe what you`ve read elsewhere . we have no plans to touragain.
"We all have our own projects going on and have families too so we couldn`t find the time even if we wanted to.
"I`m incredibly busy working on my solo record."
The Mel has ruled out any performances from the group - also consisting of Mel B, Geri Halliwell, Victoria Beckham and Emma Bunton - their famous singles will next be heard in a London stage production.
Discussing the venture, Mel B recently admitted the quintet were inspired to get on board with the production after seeing `Mamma Mia!`, which is based on the songs of ABBA.
She said: "All five of us are really super excited. We don`t do anything unless all five agree.
"All of us loved `Mamma Mia!`. We needed someone who would have a great vision alongside ours.
"It`s going to be fictional, but various characters will have traits that remind you of the group."
