It's clear that Demi Lovato is someone who has gone through some difficult times over the course of her life - not least her well-publicised heroin overdose in 2018.

However, it seems that the 'Sorry Not Sorry' singer had her fair share of trauma earlier in her life, too - as she has revealed in new YouTube docuseries 'Dancing with the Devil'.

Lovato will release her new album 'Dancing with the Devil... the Art of Starting Over' on April 2nd, and previously teased the trailer for the YouTube series.

Now, further disturbing revelations have been made in expanded footage from the series - including one segment where she says that she lost her virginity when she raped at the age of 15, working for The Disney Channel in the late 2000s.

The now 28-year-old, who rose to prominence via her roles in Disney's 'Camp Rock' films, said: "I lost my virginity in a rape. I called that person back a month later and tried to make it right by being in control, and all it did was just make me feel worse."

She did not name the offender, only to say that she had to "see them all the time" and that they "never got taken out of the movie they were in".

Harrowingly, she also revealed that she was raped by her drug dealer when she overdosed in 2018. "I didn’t just overdose. I was taken advantage of," she said. "When they found me, I was naked, blue. I was literally left for dead after he took advantage of me.

"When I woke up in the hospital, they asked if we had had consensual sex. There was one flash that I had of him on top of me. I saw that flash and I said yes.

"It wasn’t until a month after the overdose that I realised, 'You weren’t in any state of mind to make a consensual decision.'"

Lovato also admitted that she was no longer sober following her overdose, and had started to smoke weed and drink alcohol 'in moderation' - an approach that both her manager Scooter Braun and Elton John, who also appears in the series, are opposed to.

The first two episodes of 'Dancing with the Devil' are set to premiere on YouTube on March 23rd.
