Sir Paul McCartney's estranged wife Heather Mills is planning to launch an online health and beauty business later this year (07). Mills, currently embroiled in a bitter divorce battle with the former beatle, will offer fitness advice, vegan recipes and tips on how to live a green lifestyle on new website I Do Care. Mills' new career is sure to upset MCCartney, whose first wife LINDA was a vegan campaigner who launched her own vegetarian meal range. Mills is also planning to sell her own beauty products on the website, setting herself up as a rival to the former Beatle's fashion designer daughter STELLA, who has her own perfume range. A source told British newspaper the Sunday Mirror, "Heather and Stella have always disliked each other and it's her chance to get back at her. They will be upset she is promoting herself as the new Linda MCCartney."
