What did Demi Lovato say about overdose?
In the documentary trailer Lovato opened up on her near-death experience stating: "my doctors said that I had five to 10 more minutes."
She added: "I've had a lot of lives, like a cat. I'm on my ninth life."
Speaking to reporters Lovato revealed to lasting effects of the overdose.
She said: "I don't drive a car because I have blind spots in my vision," she said.
"For a long time, I had a really hard time reading. It was a big deal when I was able to read a book, which was like two months later, because my vision was so blurry."
She said the intent of the documentary was "to help people who have been on the same path as I have".
She added: "I wanted to set the record straight, and I wanted to reveal it all for my fans."
Sir Elton John also appears in the trailer and says: “When you’re young, and you’re famous, my God, it’s tough.”
