Sir Paul McCartney's wife Heather Mills MCCARTNEY will make her first catwalk appearance after a prolonged absence later this year (06). Mills MCCartney forged a successful career as a model despite losing a leg in an accident involving a police motorcycle in London in 1993, but since marrying the former BEATLE she has concentrated on campaigning for animal rights. But Mills MCCartney has now joined London-based model agency Zone. Director MIKE ILLES says, "We are delighted to be able to welcome Heather into the network of Zone models, and are very excited about the opportunity to represent her. "As well as being a well-known figure involved in headlining a number of impressive causes, Heather is an extremely talented model. "She is likely to continue to make an impact on the fashion and beauty scene."
