WWW- Beatles legend Paul McCartney is reportedly devastated to have learned that his wife Heather Mills posed naked for a German Sex Book, according to a published report.

Heather Mills, 38, posed in the 1988 book ‘Die Freuden Der Liebe’ – English translation: ‘The Joys Of Love’ – naked and doused in baby oil.

Heather is shown in one picture performing a sex act on a naked man, and in other pictures, she is shown using whipped cream, whips, and handcuffs on the same man.

McCartney is currently divorcing Mills, and a source claims that the porn pictures came as a total shock to Paul.

meanwhile on pr-inside.com: LATEST: SIR PAUL McCARTNEY’s estranged wife HEATHER MILLS has denied allegations she appeared in a “hardcore porn” shoot for a German book.

The animal rights campaigner, who found fame after losing a leg in a road traffic accident in 1993, performs a number of sexual acts in photographs in German book DIE FREUDEN DER LIEBE (THE JOYS OF LOVE), according to a report in yesterday’s (05JUN06) edition of British newspaper The Sun.

Mills readily admits she appeared in the lover’s guide published in 1988, but her lawyers insist The Sun falsely portrayed it as part of a “filthy past” of which McCartney was unaware.

A letter sent to The Sun editor REBEKAH WADE reads, “This photo shoot, undertaken approximately 20 years ago, was for the purpose of a ‘lover’s guide’ to caring relationships and instructive sex in the same way as are many other books on the market. “The photo shoot was not pornographic or for the purposes of gratification of the viewer.”

A spokesperson for The Sun responds, “The Sun was only able to publish a few images of the 172 printed in ‘Die Freuden Der Liebe’ due to the obscene and pornographic nature of the photographs. “Far from being an instruction manual, the book contains not a word of text.”

Former BEATLE McCartney and Mills – who gave birth to their baby BEATRICE in 2003 – split last month after four years of marriage.
