Every era has its heartthrobs, and the faces on bedroom posters, the smiles that sold a million magazines, the stars who made teenage hearts skip a beat. Some burned bright and vanished; others reinvented themselves away from the cameras. These are 20 forgotten teen celebs who once defined youth, fashion, and fantasy… and whose names deserve one more spotlight.
