THE HILLS star Lauren Conrad will add fashion guru to her resume in 2010 - she has written a new style guide which will be released at the end of next year. She says, "This guide will offer simple, practical tips to help anyone look fabulous." The book won't be Conrad's first - her novel, L.A. Candy, was a number one bestseller on the New York Times list and the follow-up, Sweet Little Lies, will hit stores in February (10).
