According to reports all over the internet and TMZ, pop-star Demi Lovato has been hospitalized for an apparent heroin overdose.

The reports say that paramedics found Lovato unconscious when arriving at her home. Law enforcement says that she was treated with Narcan, which is basically a ‘revival’ drug when people are dying or under from an overdose. It is very serious. The OD has been confirmed to have occurred at her home in Hollywood Hills, CA.

Demi was out Monday night celebrating a friend’s birthday in West Hollywood, and we’re told she posted photos on her private Instagram of herself and others in the group. She seemed happy in the pics.

Last month she released a song titled ‘Sober’ where she revealed that she had fallen off the sober 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.

Demi has fought substance abuse for years. This has always been a struggle that her fans are well aware of. At one point she lived in a sober living home after getting released from a drug treatment center. She had been six years sober from alcohol, cocaine, and Oxycontin.

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

At this time her condition is unknown.
