Heather Mills has denied she is writing a book of sex tips for women.

The former model - who is currently embroiled in a bitter divorce battle with Sir Paul McCartney – was reportedly planning to reinvent herself as a “sex guru” by penning a saucy self-help guide for women.

A source told Britain's Sunday Mirror: "I think Heather would like to set herself up as a female sex guru. But she is worried what people will think of her so she discussed the possibility of releasing the book under a false name.

"Heather believes there is a gap in the market for a good sex guide for women, as manuals are normally written from a man's perspective.

"She wants to give her little secrets away on how to attract a man and how to keep him happy in the bedroom. Despite the breakdown of her marriage to Paul, neither has ever said anything bad about their sex life."

However Heather's rep has dismissed the claims, saying: "Right now she is counselling cancer children in the US and trying to facilitate a bone marrow transplant to a young mother."

Should she change her mind, this won't be Heather's first foray into the sex guide business.

Earlier this year, it emerged that Heather posed naked and simulated sex for German 'educational' publication The Joys Of Love.
