Sir Paul McCartney's estranged wife Heather Mills has congratulated Paris Hilton for ditching fur, and insists her decision will have a positive knock-on effect. The ex-model and animal rights campaigner showed the formerly fur-wearing socialite gruesome videos of animal cruelty in a bid to prick her conscience. Mills is impressed to see the heiress has stuck with her promise to never purchase a pelt again, and is hopeful her fashion-conscious friends will follow Hilton's example. She says, "Paris's decision is wonderful. "As a trend setter and a fashion icon, I know she is already using her influence to persuade some of her fur wearing celebrity friends to stop wearing fur."
