Demi Lovato was rushed to a Los Angeles hospital on Tuesday after suffering an apparent overdose and is now stable. Audio of the emergency call obtained by TMZ reveals the pop star was unconscious upon the arrival of emergency personnel and revived with Narcan — an emergency medication to reverse the effects of a narcotic overdose. While TMZ reports the overdose is heroin related, a source close to Lovato told People that it is not.
… Lovato has battled addiction, mental illness and disordered eating for years. In 2010, she entered treatment, where she was treated for bipolar disorder, bulimia, self-harm and addiction. She relapsed after she left the treatment center, then entered a sober living facility for a year.
