S Club Juniors came together in Autumn 2001 following a series of nationwide auditions.
More than 10,000 kids aged between 11 and 14 entered the gruelling talent search, but only 14 got through to the final stage.
It was then up to S Club 7 to choose the lucky eight who'd be in the band - S Club Juniors.
Teacher goes on tour
Since then the band has been working hard to produce its first single.
But it's not all pop and parties. The group members have to keep up with their schooling, so two chaperones and a teacher travel with them when they're away from home.
