UPDATE: Demi Lovato is now "stable," according to a source at Variety. Earlier in the day, her aunt, Kerissa Dunn, tweeted that Lovato was "awake and responsive," but later deleted the message. A source now tells TMZ that Demi did not overdose on heroin, but did not offer further details.
Singer Demi Lovato has been hospitalized after suffering what appears to be a heroin overdose, reports TMZ. Sources say she was at her Hollywood Hills home and has been rushed to an L.A. hospital. Her condition is unknown.
“Extra” has since learned the Los Angeles Police Department received an emergency call before noon on Tuesday, and a 25-year-old female was transported to the hospital.
TMZ reports Lovato was unconscious when emergency services arrived, and law enforcement sources say that Narcan was administered on the scene.
Following the news, Demi's appearance on Tuesday's episode of "Beat Shazam" was pulled, and her July 26 concert in Atlantic City was canceled.
Lovato has been open about her battle with addiction and has sought treatment in the past.
Demi revealed she had fallen off the wagon when she released her new song “Sober” last month.
Less than 24 hours before the emergency, she posted a selfie on Instagram.
When "Extra" caught up with Demi at an event in NYC in March 2017 she opened up about her sobriety, saying, “My fans are part of the reason why I'm sober, they hold me accountable. If it weren’t for my friends, family, and fans, I wouldn’t be here today.”
She added, “My ups and downs keep me strong.”
Lovato said she also wanted to help others, “Being able to help people in recovery is something I'm passionate about.”
