Demi Lovato found making 'Child Star' to be a "healing" experience.

The 32-year-old pop singer has revealed that she relished the experience of filming 'Child Star', her documentary that centres on the potential pitfalls of child stardom.

Demi - who appeared on 'Barney and Friends' between 2002 and 2004 - told PEOPLE: "The whole journey was really healing for me. Honoring the truth of my inner child was really healing for me.

"Going back and acknowledging my struggles was honoring my inner child and holding space for my younger self ... that didn't get to live a normal childhood in my younger years."

Demi spoke to the likes of Drew Barrymore, Kenan Thompson and Raven-Symone for 'Child Star'. And the pop singer has admitted that she enjoyed spending time with people who had gone through similar life experiences.

She said: "It really created a sense of community and it made us feel less alone to share our experiences, even though we may have felt so isolated in them. So I think being able to talk to the participants of the film really was encouraging and therapeutic for me."

Demi previously claimed that the world has entered a "new era of child stardom".

The pop singer directed the documentary and she was determined to provide some "insight" into the issue.

Demi - who starred as Mitchie Torres in 'Camp Rock', the musical film, back in 2008 - told PEOPLE: "I want this to give some insight into what it's like to become a child performer, whether it's acting or through music, but in the entertainment industry because my parents didn't get that before I was a child star."
