United Kingdom, Nov. 20 -- Demi Lovato "did a lot of healing" while making Child Star.

The 33-year-old pop star co-directed the 2024 documentary, which explored the tribulations of child stardom, fame, and working in the entertainment industry at a young age, and Demi admits that it proved to be a really valuable experience for her.

Demi told Who What Wear: "I had a blast working on Child Star. But I also did a lot of healing for myself to be able to come out of that experience with some tangible change that hopefully the rest of the country will follow suit on."

The chart-topping star subsequently became a political activist for children working in the entertainment industry in the US.
