News, Lovato’s mom Dianna De La Garza and her 16-year-old sister Madison De La Garza were seen at the hospital in the afternoon.

While TMZ reported the overdose is heroin-related, a source close to Lovato claims to PEOPLE that it is not. Lovato has battled addiction, mental illness and an eating disorder for years. She entered treatment in 2010 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. Despite entering treatment, insiders say the singer continued to struggle with her private pain.
