Myleene Klass has admitted that Hear'Say were approached about reuniting on The Big Reunion but turned the offer down.
The singer-turned-TV presenter, who was this week named Best Entrepreneur at the Glamour Women Of The Year Awards, confirmed that the band had been asked to sign up for the second series of the ITV2 show.
Myleene, who was in the reality TV-formed band with Kym Marsh, Suzanne Shaw, Danny Foster and Noel Sullivan, said she would only join the show if one of her former bandmates really wanted to.
She said: "It's not for me at the moment. I couldn't do the touring again. But if one of the others really needed to do it, then I would."
The mother-of-two added: "I'd prefer if we just got together and sang together in the kitchen."
The Big Reunion was broadcast on ITV2 earlier this year and saw Five, Blue, 911, Atomic Kitten, B*Witched, Honeyz and Liberty X reform.
There had been rumours Hear'Say might appear in the next series, alongside S Club 7 and Big Brovaz.
Meanwhile Myleene, who has joined a judging panel for a reality show to choose a new Blue Peter presenter, laughed off recent headlines about her offering up her breast milk to others, saying it was a joke.
"What do you think? Have you ever breastfed? Do you know hard it is to eke out even a tiny bit? Am I really going to give it to other people?" she said.
