Rachel Zoe, a freelance fashion stylist whose clients have included the Backstreet Boys, Lindsay Lohan, Mischa Barton, Keira Knightley and Nicole Richie, is the center of Bravo's "The Rachel Zoe Project," which takes viewers into the world of celebrity dressing. Since its premiere in 2008, the show has made the 40-year-old Zoe a household name and a regular in the pages of People. Last year she stepped up from stylist to fashion designer with the launch of her own women's wear collection. She's been a consultant for Piperlime.com, collaborated with designer Judith Lieber on a collection of handbags and been the celebrity face of Samsung's BlackJack cellphone ad campaign. She shares fashion advice on the Zoe Report website and wrote a book, "Style A to Zoe," with fashion journalist Rose Apodaca.
