Supermodel Rachel Hunter believes her modelling career is nearing the end and is looking for a new direction involving nature and animals. Rod Stewart's ex-wife is currently filming movie La Cucina, due out next year (08), and hopes to write a book on motherhood. But after already trying her hand at modelling, TV presenting and acting, she is now looking to try something different. She says, "I've loved everything I've done for the past 20 years, but now, maybe, I want to do something different. I'm 37 and there's only so long you can hold on at the top of modelling. "I've always been nature driven. I love nature, I love animals, being environmental aware comes naturally to me. These are the things I love and I want to work in these fields more now."
