Sir Paul McCartney's daughter STELLA has reportedly designed a necklace featuring a single leg - in a revenge attack on Heather Mills. The fashion designer, 36, created the $600 (GBP300) pendant to launch her new jewellery collection next season. A source tells British newspaper the Daily Mirror, "A lot of people thought it was really edgy while others secretly thought it was out of order. It's such an obvious dig. It will cause a stir when it goes on sale." Mills, who lost her lost her left leg in a road accident in 1993, launched a scathing attack on the former Beatle and Stella in a string of TV interviews across the globe last week (ends02Nov07).
