Heather Mills is planning to re-launch herself as a cross between Linda and Stella McCartney.

The former model wants to revamp her image following public hostility following her split from ex-Beatle Sir Paul McCartney last year � and will launch new business �I Do Care� modelled on the green, vegetarian and fashion issues championed by his late wife and daughter.

A source tells the Sunday Mirror, �Heather's new company is going to cause fireworks in the McCartney house. She has been very cunning. On the surface, I Do Care will give her a new - caring - image. It will have information on health, beauty, green issues and veganism.

�But once it is established, she will launch a beauty range to rival Stella's. She will argue there was so much demand for it, she had no choice. But in reality, the pair have always disliked each other and it's her chance to get back at her.

"It's going to put a further wedge between her and the McCartneys. They are also going to be upset that she is trying to promote herself as the new Linda McCartney."
