Across the nation, Gen-X ironic-kitsch aficionados are racing to bookstores to pick up the new Britney Spears novel A Mother's Gift. 'Holy shit, check it out: It's about a teenage girl who becomes a pop superstar thanks to the love and support of her mother,' Mike Romanoff, 29, told friend Darius Grace, 30, while perusing the book at an Austin-area Barnes & Noble. 'This is an instant classic on par with Fabio After Dark.' Added Tim Edwards, operator of the popular 'Mr. Sarcastic' web site: 'I cannot wait to read this 'timeless, universal story as written by the girl who actually lived it.' Awesome.'
