Paris Hilton's memoir, Confessions of an Heiress: A Tongue-in-Chic Peek Behind the Pose, doesn't arrive in stores until Sept. 7, but excerpts from the book are leaking out. Among the highlights: "The rumor is that I got a credit card at age 9, which is ridiculous. It was more like 19," and "It was so embarrassing being flat-chested that I wore padded bras til I was 17. Now, I'm happy to be small. It looks better in clothes." But not in homemade sex videos.
