Apple doesn't fall far from the tree, or is it the baby doesn't land far from the bush? Whatever, Britney Spears' 16-year-old sister Jamie Lynn Spears is pregnant. Yes, you heard right, her 16-year-old sister. Preggers. Sounds so much cuter that way, huh. She's not knocked up. Jamie's preggers. Ah, how cute. Her boyfriend Casey Aldridge is the father of the baby. Man, just when you thought this family would become boring. And what a shame too, People reports that Lynne Spears book on parenting has been put on hold. I guess troubled teen moms everywhere are out of luck finding out how to get their life back on track.
