Nadine Coyle is reportedly writing a tell-all autobiography.
A source told the Daily Mirror newspaper: ''Nadine's desperate to put her side of the story across. She doesn't have a publisher yet but is planning to tout the book around for a big-money deal when it's done.
''If all else fails she will self-publish via Amazon. She's keen to boost her flagging UK profile.''
Nadine - who is expecting her first child with her boyfriend Jason Bell - is said to want to set the record straight after Kimberley slammed the Irish beauty in her recent autobiography, 'A Whole Lot Of History', claiming she created a divide in the band with her diva demands and solo career ambitions.
Kimberley wrote: ''There was a definite change in her, which became more evident each time she came back from Los Angeles.
''For a long time, the rest of us had felt that she was holding us to ransom, and with the constant whispers of Nadine's imminent solo deal, we felt as if she was calling the shots, and that the band's future was in her hands.''
The 'Can't Speak French' hitmaker also confirmed rumours of a separation between Nadine and tight-knit trio Kimberley, Cheryl Cole and Nicola Roberts, as well as dishing the dirt on Sarah Harding's addiction issues.
The novel's author saw a cut of the film and loved each of the changes the movie's director had made.
