The singer has struggled with mental illness and drug dependency for years.
Singer and competition reality TV judge Demi Lovato has reportedly been admitted to a Los Angeles hospital for a heroin overdose according to TMZ.
Police have confirmed that they responded to a 911 call to 8000 block of Laurel View Dr. just before noon on Tuesday. TMZ also confirms, "Demi was treated with Narcan -- an emergency treatment for narcotic overdoses -- at her home."
Representatives for the singer have yet to respond with a statement.
Lovato has been extremely open about her substance abuse in the past, even releasing a song called "Sober" which explores her struggles to stay away from drugs.
The documentary Simply Complicated, a film about her life, Lovato says she began to "party" in high school and continued to do so throughout her Disney days.
“My dad was an addict and an alcoholic. Guess I always searched for what he found in drugs and alcohol because it fulfilled him and he chose that over a family,” she said in the film.
In 2011 she sought treatment for bipolar disorder, bulimia, self-harm, and addiction, but relapsed and moved into a sober living facility not too long after.
She has been sober for six years.
Lovato is a huge LGBT advocate and even said in an InStyle interview, "I’m very fluid, and I think love is love. You can find it in any gender."
Her song "Cool for Summer" was also praised for its sexual ambiguity, something Lovato wouldn't admit to when asked.
“I’m not confirming, and I’m definitely not denying," she told Alan Carr in an interview when he asked about the song's meaning.
In February of this year, the San Diego Gay Men's Chorus (SDGMC) and the San Diego Women's Chorus joined the 25-year-old onstage at the Viejas Arena on her tour stop with DJ Khaled.
“Many of our singers are big Demi Lovato fans with her messages of empowerment and acceptance," Executive Director of the SDGMC Bob Lehman said at the time. "Her music is brave and strong just like we all want to be.”
