She was dismissed by a High Court judge as a fantasist who 'indulged in blatant make-believe'.

And it seems that the ever-resourceful Heather Mills intends to turn that damning indictment to her advantage.

Bound by a gagging order but determined that the truth - as she sees it - about her marriage to Sir Paul McCartney should be revealed to the world, Miss Mills seems to have found an ingenious way to let her story be told.

She has spent the past few months writing a treatment for a novel about a model who falls for a world-famous rock star and marries him before the relationship turns sour.

The book is to be touted around publishing houses with Miss Mills asking for an advance of some £1million to complete it.

While she will be adamant when promoting the book that it is fiction, the storyline and some of the main characters might appear rather familiar to those who have followed the curious twists and turns of her years with the former Beatle.

A source close to Miss Mills said: 'Heather has written the treatment for a novel about a model and campaigner who marries the most famous rock star in the world.

'She will be marketing the book as a work of fiction. But it doesn't take a genius to realise what is really behind this book - the thing which infuriated her the most about the divorce was that she was gagged from ever telling her side of the marriage.

'This is her way of getting the information out there.

'It chronicles all the model's trials and tribulations with the rock legend.

'It's a rags-to-riches tale taking in her tough childhood, how she struggled to make it as a model and then how this famous rock star met her at an awards ceremony and how they fell in love.

'She has incorporated all sorts of other characters.

'There is a hard-nosed professional woman who is part of the rock star's team who sides against the model and tries to make her life difficult - that will inevitably be seen to be Paul's divorce lawyer Fiona Shackleton.

'The rock star's first wife had passed away and his children can never get over that fact, so they gang up against the model, who they see as moneygrabbing and an opportunist.

'Those characters will inevitably seen to be based on McCartney's children Stella, Mary and James.

'The pair start rowing and the fights often end violently. The rock star is painted as a deeply flawed character whose mind has been warped by years of being treated like a god.

'He finds solace in drinking and smoking cannabis which gives him mood swings.'

Miss Mills, who was awarded £24.3million as a divorce settlement after asking for £125million, will have to tread carefully when deciding what can be borrowed from her own personal experiences as a 'model' marrying an international rock star.

But if any detail might be seen to paint McCartney in a negative light, she can just say it's fiction.
