Demi Lovato Hospitalized For Apparent Heroin Overdose

Demi Lovato was rushed to an L.A. hospital after suffering from a reported heroin overdose.

Sources say that the "Cool for the Summer" singer was transported from a home in the Hollywood Hills before noon on Tuesday, and is currently in treatment. Her condition is unknown at this time.

Demi has been open about her battle with substance abuse for several years. She recently admitted to relapsing after six years of being sober from cocaine in a song called "Sober" that was released last month.
