Heratbroken, confused......over an actor????help.?

Have any of you ever been literally heart broken that an actor/ress was dead?? I just found out thaty Heath Ledger was dead(i Know it happened a while back). BUt is it weird?? And how can such a cute guy be the Joker??? i loved it. I thought he was cuter as the jhoker, but he looks old as the Joker??
