Rachel Stevens has confessed being a guest judge on The X Factor NZ in New Zealand made her realise how much she misses her days in S Club 7.
Rachel told the Daily Mail: "It was an exciting week and great fun to be part of the show. I got quite nostalgic seeing the young bands enjoying themselves, creating new styles and sounds. It was lovely to be part of.
"I had a great time in S Club and know how much they've got to look forward to. Being back in New Zealand, albeit briefly, was a pleasure and I'm excited for Mel and for the show."
It has been rumoured that Rachel, who has a two-year-old daughter Amelie, and her S Club 7 bandmates could be getting back together for the second series of The Big Reunion.
There is also rumoured to be room on the UK X Factor judging panel as it has not been confirmed if Tulisa Contostavlos and Nicole Scherzinger will be returning, and Simon Cowell is reportedly planning a revamp to combat last year's flagging ratings.
He added: "Her feedback was incredibly valuable to the contestants and to Mel having been very successful in a band herself. Plus she was a natural in front of the camera."
