Perhaps some of Britney's reluctance comes from seeing her little sister, Jamie Lynn Spears, have to face so much public scrutiny over her recent pregnancy. "I was shocked a little bit," says Brit. "She’s always been the baby, and now the baby was having a baby. It was mind-boggling."Though Britney may have been shocked by her sister's pregnancy, she soon came around after reading the galleys from her mother's upcoming book, The Lynne Spears Guide to Fucking Up Your Children. After reading Chapter 10 ("Babies Having Babies Having Increased Earning Potential"), Brit-Brit kicked up her feet and opened a brand-new, celebratory bag of Cheetos Cracker Trax.
