In early 2004, Paris Hilton began selling a book about herself, "Confessions of an Heiress: A Tongue-in-Chic Peek Behind the Pose", which was mostly written by Merle Ginsberg. The book has hundreds of photographs of her and contains her advice on life as an heiress. Hilton reportedly received a $100,000 advance payment for this book. The book was made fun of by Robert Mundell on The Late Show with David Letterman. The book became a New York Times bestseller. Hilton then made a designer diary, also mostly made by Merle Ginsberg, called "Your Heiress Diary: Confess It All to Me".
