Yeah I heard this too and I was completely shocked! Its such a shame!
They said he had pneumonia when he died so maybe it was an accidental overdose. Though he was very depressed because of his break up with his fiance (which was because of his drug addiction). But of course this is all radio talk so who knows if it is true. And the Mary Kate thing was that the massage lady called her friend when they found him dead because her friend is an EMT and he happens to be Mary Kate's body guard <img src="i/expressions/face-icon-small-smile.gif" border="0">
I feel so bad for the family and his daughter. She is adorable!
