The latest "docu-series" features 12 high schoolers whose lives are forever altered by pregnancy, motherhood and TV fame. The storylines range from a youngster whose baby daddy tragically drowned to a model and cage fighter forced to the sidelines by her growing belly. Plus: More cheerleaders than ever!
