The explosive book would detail every aspect of the couple"s three-year relationship and Jack has told publishers he will not omit anything.
Meanwhile, it has emerged that Jade Goody, who died aged 27 on Sunday, left her new husband nothing in her 4-million pound will. Instead Jade has left her fortune to her two boys, Bobby, five, and Freddy, four.
However, pals are now warning Jack Tweed that it would not look too good if he is seen to be selling his story right after his wife"s death.
“This is the book that the whole nation wants to read. Jade Goody"s story and her subsequent death has been the biggest story we have seen in recent times and Brits are desperate for the next instalment," The Daily Star quoted a publishing insider, as saying.
"This book will be that and the publishing deal alone will be huge, let alone the serialisations that will appear in newspapers. Jack Tweed could net an absolute fortune for this and he needs to make sure he has got good advisers in place to do the deals for him," the source added.
