Pop singer Demi Lovato is 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, but reports say that date has now been cancelled.
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.

My friend @ddlovato is one of the kindest, most talented people I’ve ever met. Praying for her right now, addiction is a terrifying disease. There is no one more honest or brave than this woman.

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.
Lovato released her first studio album, Don’t Forget, in 2008.
In a YouTube documentary, Simply Complicated, released last October, Lovato revealed her drug use began when she first tried cocaine at the age of 17.
“I felt out of control the first time I did it,” she said. “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.”
Lovato went to rehab for the first time in 2010.
“I wasn’t ready to get sober,” she said in the documentary.
“I was sneaking it on planes, sneaking it in bathrooms, sneaking it throughout the night”.
