Singer Demi Lovato stable after suspected drug overdose

Pop music star Demi Lovato, who has spoken openly about her history of drug and alcohol abuse, was taken to a Los Angeles hospital on Tuesday (July 24) suffering from a suspected overdose, according to media reports.

Representatives for Lovato, 25, did not respond to a request for comment but People magazine, quoting an unidentified source, reported she was "okay and stable."

The magazine later updated its account, quoting a source as saying the Grammy-nominated recording star was "awake and talking."

TMZ, quoting law enforcement sources, reported that Lovato was found unconscious at her home and was treated with Narcan, an emergency antidote for suspected opioid and drug overdoses.

Los Angeles police said they had responded to a medical emergency on Tuesday involving a woman on the Hollywood Hills street where Lovato reportedly has a home but declined to identify the person.

City fire department spokeswoman Margaret Stewart said a 25-year-old woman was transported to a local hospital from that location.

Lovato released a song last month called Sober in which she sang: "Momma, I'm so sorry, I'm not sober anymore, And daddy, please forgive me for the drinks spilled on the floor, To the ones who never left me We've been down this road before, I'm so sorry, I'm not sober anymore."

In a 2017 YouTube documentary, Simply Complicated, Lovato spoke about years of substance abuse, eating disorders, and drinking, saying she first started using cocaine when she was 17.

She entered rehab at the age of 18, where she was diagnosed with bipolar disorder.
