They haven't birthed one superstar yet. Camila's success is a fluke because she's following J.Lo's blueprint (being a terrible Latina singer who sleeps her away around for relevancy and success). Normani has yet to launch her official solo efforts, which is the one who really has the potential to be a superstar. Lauren and Dinah Jane should fare well as stars (similar to Kelly Rowland level). I forgot who the other one is.
