Demi Lovato Met with Love and Support From Hollywood After Overdose

Stars speak out in shock, sadness and support as news spreads about the "Sober" singer being rushed to the hospital.

UPDATE at 6:00am PT on July 25, 2018: Though law enforcement sources told TMZ Demi's OD was an apparent heroin overdose, a source close to Demi said it was NOT heroin. Overnight, ex-boyfriend Joe Jonas and close friend Nick Jonas also shared new messages of support.

Demi Lovato has no shortage of famous fans wishing her well in wake of her hospitalization for a heroin overdose on Tuesday.

Ariana Grande, Ellen DeGeneres, Missy Elliott, Bella Thorne and Brad Paisley were among the first celebrities to share their shock, sadness and support for the pop star as the news spread.

Law enforcement sources told TMZ that Demi was transported from her home located in the Hollywood Hills just before noon and is currently being treated. As of now, her condition is unknown.

According to TMZ, paramedics found Demi unconscious when they arrived. They then treated her with Narcan -- an emergency treatment for narcotic overdoses. Demi was reportedly out Monday night celebrating a friend's birthday in West Hollywood, where she seemed happy and in good spirits.

Last month, the 25-year-old singer released a song called "Sober," in which she revealed she had fallen off the wagon after being six years clean from alcohol and cocaine.

Demi has been extremely forthcoming about her battles with substance abuse and bipolar disorder, opening up about both in her 2017 YouTube documentary, "Simply Complicated."

"You have to lean into the people who are trying to support you," she said in the film. "You really have to surrender because that's when the change is going to happen."

The pop star was living in a sober-living home while she was a judge on "The X Factor" from 2012 to 2013.

Back in March, Demi spoke with Billboard about her disastrous time at the 2016 Met Gala and said someone at fashion's biggest night drove her straight to attending an AA meeting.
