Liberty X star Jessica Taylor is hoping the band's comeback will help bring closure for her.
The band - who formed back in 2001 - are joining forces once again for new TV show The Big Reunion alongside acts such as Atomic Kitten and 5ive.
Jessica told the Sun of her decision to take part: "What swung it for me was that it would be a good way to get closure. People didn't know we had finished. We just quietly disappeared.
"This will be a big bang. I will always cherish the memories. It was the most fun time of our lives and to recapture a bit of that would be amazing."
But the singer - who has a three-year-old son Dylan with cricketer husband Kevin Pietersen - admitted the reunion was a bit daunting.
"I felt very safe in my little bubble of motherhood and domesticity. It's quite scary to contemplate going back into the public eye," she added.
