A short while after TMZ reported that Demi Lovato had suffered an overdose and was hospitalized, a death hoax surfaced on social media.

And following reports that Demi Lovato was rushed to hospital on Tuesday for a suspected heroin overdose, sources claim her ex-boyfriend Wilmer Valerrama is "completely devastated".
