TMZ is reporting singer Demi Lovato has been rushed to hospital, suffering from an alleged heroin overdose.
Demi Lovato, who broke out in 2008 with the Jonas Brothers in Disney's movie Camp Rock, has been a recovering addict for quite some time.
She entered a treatment facility in 2010 for physical and emotional issues, and in 2013 lived in a sober-living facility.
Recently, she released a single called "Sober", in which she confesses she's fallen off the wagon.
Her condition is unknown.
