According to The Blast, Demi Lovato might have been on meth at the time of her overdose. Sources close to her say it was not on overdose of heroin.

Police officials told The Blast that illegal drug paraphernalia and drug remnants were found at the singer’s home when paramedics arrived on Tuesday, though it’s unclear what kinds of drugs were present at the scene as there may not have been enough left for analysis.

TMZ reports that the incident occurred after an all-night party at her home and that she refused to divulge what drug she’d overdosed on except to adamantly deny that it was heroin.

“Demi is awake and with her family who want to express thanks to everyone for the love, prayers and support. Some of the information being reported is incorrect and they respectfully ask for privacy and not speculation as her health and recovery is the most important thing right now,” the singer’s rep said in a statement Tuesday.
