We spotted Lindsay - where else? - on the set of Labor Pains running over her lines and fine-tuning her performance with a costar yesterday afternoon. Of course, we've been hearing plenty of gushing over Lindsay's dramatically improved work ethic for a while now - but we're still thrilled to see Lindsay puttin' it into action!
