David Oldfield has remained tight-lipped on his split from wife Lisa so far, after they called time on their 18-year marriage in February.
But the One Nation co-founder, 61, looks set spill some family secrets in his new memoir, Before You Judge Me, which appears to have riled Lisa, 44.
The former Real Housewife of Sydney mocked the release on Instagram over the weekend, as David tells Daily Mail Australia nothing is off limits in the book.

'It's very personal, very honest, and in places it is very raw,' said David last week, confirming the book will discuss his tumultuous personal life.
He added that his account of things will be 'completely honest' yet 'self-deprecating' while covering his new 'responsibilities as a single dad' with parenting in general.
David said the book will touch upon 'the ugliness of politics', with a chapter on Tony Abbott, and 'very descriptive' chapters on 'the real' Pauline Hanson.
Additionally, it will also look back at his five separate reality TV outings, career as a broadcaster at 2UE and 2GB and his 'experiences in life and death situations'.
'It's very personal [and] very honest about everything,' David told Daily Mail Australia last week of memoir Before You Judge Me, following the end of his 18-year marriage to Lisa in February
