Whoa! Pop star Demi Lovato has been hospitalized in Los Angeles, after suffering what is being reported as a heroin overdose.

According to TMZ, the 25-year-old was transported from her home in the Hollywood Hills just before noon Tuesday (July 24), and is currently being treated.

However, her current condition is unknown.

Demi has apparently fought substance abuse for years, and once lived in a sober living home after getting released from a treatment center. She’s said to have been six years sober from cocaine.

In a song called “Sober”, which she released last month, Demi said she had fallen off the wagon.

Stay tuned for updates.
