Demi Lovato says she had a heart attack and 3 strokes after an overdose

• Demi Lovato said she suffered three strokes and a heart attack after her 2018 overdose.
• She said doctors told her she was less than 10 minutes away from death.
• Lovato plans on sharing the full details of her overdose and battle with addiction in her upcoming documentary "Demi Lovato: Dancing with the Devil."

Demi Lovato has shared for the first time that she suffered a heart attack and three strokes after a nearly fatal overdose in July 2018.

Lovato described her near-death experience in a new trailer for her upcoming YouTube documentary, "Demi Lovato: Dancing with the Devil."

The experience left her temporarily blind, and she said her doctors told her she was less than 10 minutes away from death.

The star had been in recovery for six years before her relapse and subsequent overdose. Lovato told Ellen DeGeneres in a 2020 interview that, when she asked her team for help before her overdose, they called her "selfish."

"Every time you suppress a part of yourself, it's gonna overflow," Lovato said in the trailer.

While the singer and actress has been candid about her struggles with drug and alcohol addiction and recovery in the past, the new film will track her journey from child star to world pop star, and all of the pressures that came with it.

"I've had so much to say over the past two years wanting to set the record straight about what it was that happened," Lovato said in the trailer. "I've had a lot of lives. Like my cat, you know? I'm on my ninth life."

The documentary will premiere on March 23 in a four-part series.
