Pop singer Demi Lovato is in a Los Angeles hospital after a suspected drug overdose.

US media report that the Los Angeles Police Department reportedly responded this morning 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 after possibly taking heroin.

The Sorry Not Sorry singer was in a stable condition.

Lovato has struggled with substance abuse for years, and appeared to relapse 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.

The BBC contacted Lovato’s representatives this morning, but did not receive an immediate reply.

As reports of her condition spread, there was an outpouring of support on social media from other celebrities and musicians.
