Lauren Conrad is best known for her starring turn on the MTV reality series "The Hills," but she also has multiple bestsellers to her credit. In addition to her TV work, she's the author of "The Fame Game" and the "L.A. Candy" series of novels. She's also a clothing designer who last year published the fashion guide "Lauren Conrad Style." This October, she offers a companion guide, "Lauren Conrad Beauty" (HarperCollins: 288 pp.: $21.99, ages 14 and up), in which she teaches women of all ages how to be the best versions of themselves with tips on hair and skin care, diet, exercise and makeup.
