It was Princess Diana for me. All the deaths listed above are tragic. No one expects celebrities to die - they always seem invulnerable. Of all the ones I've been alive to see (I am 41), Diana's was the only one that really made me shed tears. One picture I recall of her was when she put on a kevlar vest and visited a country where land mines were everywhere. She did that to bring them to the attention of the world. How many other celebs would do that? I miss that compassion in the world.
