Pop singer Demi Lovato is now awake and with her family in a Los Angeles hospital after a suspected drug overdose, US media report.
The Los Angeles Police Department reportedly responded on Tuesday to a medical emergency in the Hollywood Hills, where Lovato lives.
TMZ reports the 25-year-old was found unconscious and treated at the scene with Naloxone, an anti-overdose medicine.
The Sorry Not Sorry singer was in a stable condition, US media report.
She was alert and breathing at Cedars-Sinai Medical Center.
Her spokesperson told the BBC: “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.”
Lovato has struggled with substance abuse for years, and was feared to have relapsed in recent weeks.
Last month she cancelled her show at London’s O2 arena, announcing the news on Twitter hours before the concert was due to begin.
In a single released last month, Sober, she sings: “Mommy, I’m so sorry I’m not sober anymore. And daddy please forgive me for the drinks spilled on the floor.”
The song ends with the lines: “I’m sorry that I’m here again, I promise I’ll get help/It wasn’t my intention, I’m sorry to myself.”
The track release followed Lovato marking six years of sobriety in March this year.
She was due to complete the North American leg of her Tell Me You Love Me world tour with a concert in Atlantic City, New Jersey, on Thursday.
Her fans say the singer’s battles with bipolar disorder, bulimia and addiction – often documented in her music – have helped them with their own struggles.
As reports of her condition spread, there was an outpouring of support on social media from other celebrities and musicians.
Within hours of the report, tens of thousands of people had tweeted the hashtag #PrayforDemi.
According to US health officials, 115 Americans die from an opioid overdose every day with more than 250,000 Americans dying over the past decade.
I love @DDLovato so much. 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.
