A U.K tabloid has unearthed some more old pictures of Heather Mills posing in the buff.

But it wasn't just her clothes that Sir Paul McCartney’s ex jettisoned for the 1999 shoot.

Heather appears naked and without her artificial leg in black-and-white photos originally designed to promote her anti-landmine charity work.

However, they never saw the light of day – until now.

A source explains to the News Of The World why: "…Heather figured Paul would take a pretty dim view if suddenly a load of nude pictures of her came out. It wasn't just this shoot she worried about - there was the infamous porn-style German sex manual she starred in too.

"Quite a few people got phone calls and she made it very clear that the McCartney legal team would come down like a ton of bricks if the pictures ever went public."

Last year a newspaper uncovered explicit full frontal shots of Heather, allegedly taken during her days as a 'glamour model'.
