Happy birthday, Lauren Conrad! The former reality TV star, now best-selling-author and designer, turns 29 today. As a teenager, the Southern California girl had always known that she wanted to work in fashion. Leave it to MTV to turn Conrad and her friends into overnight sensations with the cult classics Laguna Beach and The Hills. Not long after, the lifestyle guru launched her clothing line and began writing, topping bestseller lists. Most recently, the go-to style icon tied the knot with William Tell in a very chic vineyard locale. From her personal style to her enviable penthouse, the fashionista is an inspiration to all of us.
