Star stories: It's good to be a celebrity. It's even better to be a celebrity with a book. They sell. Four new star memoirs have entered USA TODAY's Best-Selling Books list this week. Rocker Steven Tyler tops the celebrity entries at No. 7 with Does the Noise in My Head Bother You? He's followed by singer Shania Twain at No. 16 with her From This Moment On, Betty White's If You Ask Me (and I Know You Won't) at No. 22 and Dick Van Dyke's My Lucky Life In and Out of Show Business at No. 75. They join a couple of other celebrities whose memoirs made the list earlier this month: Tina Fey's Bossypants at No. 8 and Rob Lowe's memoir at No. 12.
