Lovato said she celebrated six years of sobriety in March, but a recent song hinted that she was no longer sober.
LOS ANGELES — Grammy-nominated pop star Demi Lovato was hospitalized in Los Angeles on Tuesday after an apparent drug overdose from an unspecified narcotic, two sources familiar with the incident told NBC News.
The singer, 25, was rushed from her home in the Hollywood Hills neighborhood to Cedars Sinai Medical Center, where sources said she was stable, alert and breathing.
First responders who were called to Lovato's home used naloxone, an opioid-overdose antidote, to reverse the effects of the overdose, the sources said.
The news was first reported by TMZ, which had originally said Lovato had overdosed on heroin, but then backtracked and said it was another drug.
Lovato has been open about her battles with addiction, including a stint in rehab for issues related to an eating disorder and self-harm.
She said she celebrated six years of sobriety in March.
"So grateful for another year of joy, health and happiness," Lovato tweeted on March 15. "It IS possible."
But in a song released last month, she seemed to suggest that she had relapsed. The track, "Sober," included lyrics such as: "I'm so sorry I'm not sober anymore" and "I promise I'll get help."
Legions of fans — including several celebrity admirers — posted words of support on social media.
"I love @DDLovato so much," Ellen DeGeneres tweeted. "It breaks my heart that she is going through this. She is a light in this world, and I am sending my love to her and her family."
