Demi Lovato Is Said to Be Hospitalized for Drug Overdose

Demi Lovato, the Grammy-nominated pop singer known for her big voice and confessional nature, was rushed to a Los Angeles area hospital on Tuesday afternoon after experiencing what the authorities said was a drug overdose, according to news reports.

Representatives for the Los Angeles Police and Fire Departments said that officers responded just before noon local time to a medical emergency in the Hollywood Hills. Paramedics transported a 25-year-old woman in stable condition to the hospital, a Fire Department spokesman said, though the authorities declined to identify the person.

TMZ and NBC News reported that the patient was Ms. Lovato, 25, who has frequently discussed her struggles with substance abuse in both music and interviews.

Kerissa Webb Dunn, an aunt of Ms. Lovato, wrote on Facebook: “PLEASE PLEASE pray for my sweet niece DEMI LOVATO. She has been hospitalized and needs everyone’s prayers desperately!!!! PLEASE PRAY she pulls through.” She added later that Ms. Lovato was “awake and responsive.”

Citing the concert promoter Live Nation, a representative for the Atlantic City Beach venue where Ms. Lovato was scheduled to perform on Thursday told The Press of Atlantic City that the singer would not appear. Fox said in a statement that an episode of the game show “Beat Shazam” that was scheduled to feature an appearance by Ms. Lovato on Tuesday had been postponed.

A representative of Ms. Lovato’s said in a statement on Tuesday night: “Demi is awake and with her family who want to express thanks to everyone for the love, prayers and support. Some of the information being reported is incorrect and they respectfully ask for privacy and not speculation as her health and recovery is the most important thing right now.”
