Demi Lovato was rushed to an L.A. hospital after suffering what appears to be a heroin overdose, law enforcement tells TMZ.

Our sources say Demi was transported by ambulance from a home in the Hollywood Hills just before noon Tuesday, and is currently being treated. We do not know her condition.

Demi has fought substance abuse for years ... at one point she lived in a sober living home after getting released from a treatment center. She had been 6 years sober from alcohol, cocaine and Oxycontin.

Last month she released a song called "Sober" where she revealed she had fallen off the wagon.

Demi just performed on Sunday at the California Mid-State Fair in Paso Robles with Iggy Azalea.

She was scheduled to go on the road this week for an upcoming show in Atlantic City, but our sources say she's been struggling.
