Nadine, Cheryl Cole, Nicola Roberts, Kimberly Walsh and Sarah Harding have all contributed to the biog detailing their unstoppable rise from pop wannabes.

And pals say straight-talking Nadine (23) may use it to get revenge on Jesse for breaking her heart.

The pair met in February 2006, but split briefly last November due to the pressures of a long-distance relationship.

They got back together, but then broke up when Desperate Housewives star Jesse was spotted with a mystery woman in LA.

The break-up came as a real blow to Nadine who had not only moved with her family to LA, but also stood by Jesse during his spell in rehab for drink problems.

Girls Aloud are reported to be raking in a cool £15m for their sell-out Tangled Up tour which runs right through to the middle of September.

In between, they have been busy finalising the book, which is expected to be released by publishers Transworld in October.

"The book will be a frank account of their rise to the top and none of the girls will be sweeping anything under the carpet," one insider told Sunday Life.

"Obviously there is a lot of interest in Nadine and Cheryl and you can take it they have plenty to write about."
