Demi Lovato's aunt, Kerissa Webb Dunn, posted on Facebook that her niece was "awake and responsive" but has since deleted the status update.
Before that she wrote, "PLEASE PLEASE pray for my sweet niece DEMI LOVATO. She has been hospitalized and needs everyone's prayers desperately!!!! PLEASE PRAY she pulls through." That update still remains on her Facebook page.
However, both Variety and People are citing sources that told them the singer is "stable."
Demi Lovato has been hospitalized after suffering what appears to be a heroin overdose, according to TMZ.
Law enforcement sources told TMZ that paramedics found the singer unconscious when they arrived at her home in the Hollywood Hills, then transported her to a Los Angeles hospital just before noon on Tuesday. She is currently being treated, but her condition is unknown.
As a result, Fox has decided to pull her episode of Jamie Foxx show "Beat Shazam" from Tuesday's schedule.
"Tonight's previously scheduled episode of 'Beat Shazam' featured a guest appearance by Demi Lovato," Fox said in a release. "In light of recent reports, we have decided to replace the episode of 'Beat Shazam' with another all-new episode. Our thoughts go out to Demi and her family."
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 sober from alcohol and cocaine.
Throughout the song, she apologizes to those who may be disappointed in her for slipping back into old habits. The music video showed photos and video footage of her partying with friends.
"I got no excuses, for all of these goodbyes / Call me when it's over, 'cause I'm dying inside," she sings. "Wake me when the shakes are gone and the cold sweats disappear / Call me when it's over and myself has reappeared."
Looking to her family, she continues, "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."
After apologizing to the men in her life, Demi then turns to her fans: "I'm sorry for the fans I lost, who watched me fall again / I wanna be a role model, but I'm only human."
The song ends with Demi singing, "I'm sorry that I'm here again, I promise I'll get help / It wasn't my intention, I'm sorry to myself."
Demi has been extremely forthcoming about her battles with both 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-lving home while she was a judge on "The X Factor."
Back in March, she spoke with Billboard about her disastrous time at the 2016 Met Gala and explained why fashion's biggest night drove her straight to attending an AA meeting.
"I had a terrible experience," she said, with the author noting how her voice rose in pitch "for the only time during [their] conversation."
"This one celebrity was a complete bitch and was miserable to be around," Demi explained. "It was very cliquey. I remember being so uncomfortable that I wanted to drink."
According to Demi, she went to a 10 p.m. Alcoholics Anonymous meeting right after the event.
"I changed my clothes, but I still had my diamonds on -- millions of dollars of diamonds on in an AA meeting," she explained. "And I related more to the homeless people in that meeting who struggled with the same struggles that I deal with than the people at the Met Gala -- fake and sucking the fashion industry's dick."
