Saddest Celebrity Death Countdown.

I remember watching a countdown of the most tragic deaths in Hollywood in 2010 or 2011, and I don't even see a record of it anywhere. i've been trying to find it but unfortunately I don't remember the exact airdate of it. Does anybody know what I'm talking about? I remember that Karen Carpenter was #8,, and I included the link about Karen Carpenter here: https://www.youtube.com/watch?v=8A1RWAq-Prs. I also remember that Marilyn Monroe, Princess Diana, and Gary Coleman were in it (The latter had recently died, I believe).
