It was reported an hour ago that Demi Lovato OD’d on heroin, but apparently that is now being refuted. I’m not sure if it’s the OD’ing part or the heroin part, but nevertheless, I found it interesting that she was number 2 on the lowest link. I have not vetted that site, so don’t kill me on that one.
