Singer Demi Lovato has reportedly been hospitalized in Los Angeles following a drug overdose, TMZ first reported Tuesday afternoon.

Lovato, who has a history of struggling with substance abuse, has sought treatment in the past and released a new song, "Sober," in June.

Lovato was six years sober from cocaine usage when she released "Sober," in which she sings about the difficulty of staying clean.

Momma, I'm so sorry, I'm not sober anymore And daddy, please forgive me for the drinks spilled on the floor To the ones who never left me We've been down this road before I'm so sorry, I'm not sober anymore

The song also apologizes to fans, friends, and at least one ex who witnessed her addiction and difficulty.

TMZ reports that Lovato is currently being treated for "what appears to be" a heroin overdose, and she was unconscious when paramedics arrived.

Lovato currently has a concert scheduled for Thursday in New Jersey. Mashable has reached out to her representatives for comment.
