Sixteen year old mom-to-be Jamie Lynn Spears has purchased a new truck for boyfriend Casey Aldridge, so that can drive her and their baby around without looking like a bum. The couple were spotted shopping for used vehicles on a lot in Tupelo, Mississippi earlier this month, before settling on a white Nissan truck with a trailer hitch, Life & Style Magazine reports. Car salesman Mitch Savery says: “Their main concern was having a safe car with power. They were planning on using it for fishing trips.”
