Demi Lovato appears to be telling-all about her infamous 2018 drug overdose in a new documentary entitled Dancing with the Devil, in which she reveals shocking details about the near-death experience that saw her hospitalised for two weeks.
"I had three strokes," Lovato says in the trailer for the upcoming feature.
"I had a heart attack. My doctors said that I had five to 10 more minutes."
The clip, which features Lovato's parents, sister, friends and celebrity appearances from Christina Aguilera and Elton John, dances around the subject of what drug Lovato took that caused the medical emergency - widely believed to be heroin.
"I crossed a line that I had never crossed," Lovato says in an interview.
Her friend, actor Matthew Scott Montgomery, is then shown saying: "Are we talking about heroin? Are we doing that?"
Lovato's mother Dianna De La Garza then describes watching all of her daughter's blood "come out of her body into a machine" during her time in hospital.
The 'Cool for the Summer' singer was revived with Narcan by paramedics who were called by a friend when Lovato was discovered unresponsive at her Hollywood Hills home.
A month before her overdose, Lovato had released the track 'Sober', in which she sings about how she had relapsed after six years clean from drugs and alcohol due to addiction.
Dancing With The Devil will also address Lovato's short-lived engagement to actor Max Ehrich, as evidenced by a gleeful Lovato declaring "I'm engaged!" while showing off a huge diamond ring, before switching to a shot of the singer holding up an empty ring finger while pulling a face.
The four-part YouTube documentary is set to be released on March 23.
