Heather Mills plans to write a novel

Heather Mills is reportedly planning to write a novel about a model's marriage to a famous rock star.

According to the Daily Mail, she intends to write the "work of fiction" to shed light on her marriage to Sir Paul McCartney.

As part of her £24.3 million divorce settlement, Mills was instructed not to reveal her side of the story to the press.

A source said: "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."

The insider added: "She has incorporated all sorts of other characters. 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 money-grabbing and an opportunist.

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

The rock star in the book is said to be a "deeply flawed character whose mind has been warped by years of being treated like a god".
