A Los Angeles Police Department spokesman told the Press Association that its officers were called to an address in Hollywood at around 11:00am local time on Tuesday.
The spokesman said a 25-year-old female was in the process of being taken to hospital when the officers arrived and is in a stable condition.
Entertainment Tonight reports that they have been told by a number of sources that the star is being treated for a suspected drug overdose.
Lovato, who has openly discussed her battles with addiction, depression and eating disorders, released her new song Sober last month. After six years of sobriety, the ballad’s lyrical content raised concerns about Lovato’s health.
If you have been affected by any of these issues please contact the Samaritans on 116 123.
Among the fans sending their best wishes were presenter Ellen DeGeneres and singer Ariana Grande:
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.
