People magazine reports singer Demi Lovato was found unconscious Tuesday after an apparent overdose.
A source says Lovato is now in stable condition.
TMZ reports that she was revived at her Los Angeles home after being treated with the opioid-reversing drug narcan after her overdose.
While TMZ reports the overdose is heroin-related, a source close to Lovato claims to People that it is not.
The 25-year-old recently celebrated six years of sobriety before revealing a drug relapse last month in the song "Sober."
