Demi Lovato was rushed to an L.A. hospital after suffering what appears to be a heroin overdose.
TMZ broke the story after law enforcement confirmed to them.
Sources say Demi was transported from a home in the Hollywood Hills and is currently being treated. Her condition is unknown.
Demi has fought substance abuse for years, at one point she lived in a sober living home after getting released from a treatment centre. 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.
