The 'Reach for the Stars' group - Hannah Spearritt, Paul Cattermole, Jo O'Meara, Rachel Stevens, Tina Barrett, Jon Lee and Bradley McIntosh - have signed a new record deal and are planning a tour and even possibly a new album together.
A source told the Daily Mirror newspaper: ''The guys have been inundated with approaches and offers over the past three years, but always said no.
''But following a series of talks and meetings, they decided to go for it.
''The band figured it was a case of now or never. And if the gigs go well there is the option to release a new album, plus a Greatest Hits.
''Everyone is really excited - and frantically getting back in shape.''
S Club 7 were formed by ex-Spice Girls manager Simon Fuller and rose to fame in 1998 starring in their own TV show 'Miami 7' and having a parallel pop career. They scored four UK number one hits and sold over seventeen million albums worldwide before initially splitting in 2003.
The group were brought back together again for the first time in London last March to celebrate former member Jon Lee taking over the starring role of Frankie Valli in the musical 'Jersey Boys', sparking rumours they would get back together.
