Cheryl Cole has revealed none of her Girls Aloud bandmates have bothered to thumb through her autobiography.
The singer published her memoir, Cheryl: My Story, two months ago as she was working on her reunion with the group.
But as she appeared alongside the chart-toppers on The Graham Norton Show, she said they had all avoided looking through a copy.
"Not one of them has read it," said Cheryl, adding: "They don't need to as they were there."
She also confirmed that a return to ITV's the X Factor had been ruled out.
"It's a definite no," she told presenter Graham.
Bandmate Kimberley Walsh - currently a contestant on Strictly Come Dancing - said the future of the group was still undecided.
"We don't know. We'll see how the tour goes. We hope it is a success."
