The first trailer for Demi Lovato‘s upcoming docuseries, Demi Lovato: Dancing With the Devil, reveals terrifying details about her 2018 overdose. Doctors feared that the “Confident” singer, then 25, wouldn’t survive after she suffered three strokes and a heart attack during the ordeal. “I had crossed a line that I had never crossed before… I snapped,” Demi shares in the trailer. “My doctors said that I had five to 10 more minutes [to live].”
