In the upcoming Hulu documentary 'Child Star,' Demi Lovato reveals the harsh realities of growing up in the spotlight, including claims that 'popular girls' at school signed a suicide petition urging her to end her life. Lovato, along with other former child stars like Drew Barrymore and Raven-Symoné, reflects on the emotional and physical toll of early fame in the documentary, which marks Lovato's directorial debut. The trailer highlights the lack of guidance for young actors navigating the industry, with Lovato stating, 'There definitely is not a manual on how to navigate this industry at such a young age.' She acknowledges that while she wouldn't change her journey, it came at a significant cost. The documentary is set to premiere on September 17 and aims to explore the highs and lows of child stardom, addressing sensitive topics such as mental health and substance abuse.
