Lauren Conrad turns 24 today after kicking off the celebrations last week in Vegas at the launch of her second book, Sweet Little Lies. Lauren burst onto the scene as the star of Laguna Beach: The Real Orange County in 2004. Since then she has expanded to become the head of her own mini-empire after the success of The Hills, her clothing lines, a partnership with Mark, and a book series. She may not be on reality TV anymore, but LC is one starlet we still love to watch!
