Pregnant teen star Jamie Lynn Spears has bought her boyfriend a new truck - so he can drive her and their baby around in style. The 16-year-old actress and boyfriend Casey Aldridge were spotted shopping for used vehicles on a lot in Tupelo, Mississippi earlier this month (Jan08). Aldridge drove off in a white Nissan truck with a trailer hitch, according to Life + Style magazine. Car salesman Mitch Savery says, "Their main concern was having a safe car with power. They were planning on using it for fishing trips."
