Back in July, Demi Lovato overdosed on a substance that was then thought to be heroin but and since been speculated all over the map, from Oxycontin, to meth, to "not pharmaceutical." What people now believe to be the cause of the OD is a bit of fentanyl mixed in (a mixture that's been implicated in many other celebrity deaths including Mac Miller and Prince). The guy who gave her the drugs said this of them (it's worth it to watch the video where he says this just to see how out of it the guy is, with another very high guy wandering around behind him and touching a tree. ):

"A hundred percent she knew what she was taking. I had disclosed to her that these are not, you know, pharmaceutical. They're much stronger. She understood fully... It was unfortunate what happened. For people to think that there was any misconception on my behalf is absolutely ridiculous."

Now, months later, so-called fans are telling Ms. Lovato who she can and can't be friends with on social media. A fan wrote that firing former dancer Dani Vitale was "completely unfair" and that "she’s one of the few who really cares about Demi’s health." Maybe so, although I don't know how this Demi Lovato fan account admin would know such personal information. Lovato brought the social-media speculator to London-town with this shut-down comeback:

The dancer also seems very obviously guilty of supplying drugs based on her outrageous denial: "I have NEVER touched nor even SEEN a drug in my entire life." Ok.
