However, Louise Redknapp quashed the possibility of an imminent reunion on Monday when she categorically denied that the former bandmates had signed a deal to star in next year's edition of the ITV series, The Big Reunion.
"Louise has not ruled out doing something with Eternal and would love the chance to do something with the girls at some point," a spokesperson told the Mail Online. "She has been overwhelmed at the outpour from fans wanting to see them perform again."
'However, when the time is right she would want it to be something a bit more natural and not for the purpose of a TV show so has ruled out taking part in The Big Reunion.'
Louise - the wife of footballer pundit Jamie Redknapp - famously left the bandmates Easther and Vernie Bennett and Kéllé Bryan in 1995 to launch her own solo career, and has since moved into TV and modelling.
She was rumoured to have signed a deal worth £500,000 to appear on the show.
5ive, B*Witched, Atomic Kitten, Honeyz, 911 and Liberty X all took part in the first series of The Big Reunion, which proved to be an unexpected hit with viewers.
Mum-of-two Louise has previously said that she had no intention of appearing on the programme. “It would be fun, but if Eternal were ever to get back together it would be a new song with a real purpose rather than just a TV thing,” she told the Mirror back in May. "I wouldn’t be upset at all if the girls wanted to reunite without me."
Eternal formed in 1992, and after Louise left continued as a trio until 1998. Their hits included Oh Baby I, Just a Step from Heaven, and Power of a Woman, and their 1993 Always and Forever album was the first album by a female group to sell more than one million copies in the UK.
Louise, meanwhile, went on to enjoy success as a solo artist, with singles including Naked, Arms Around the World and a cover of Stuck in the Middle With You.
