Nightbirde, the America's Got Talent singer whose real name was Jane Marczewski, passed away at the age of 31 after a "brutal" cancer battle. She had shared her experience battling the disease on social media while getting down to just 85 pounds at one point. Nightbirde had become an overnight sensation last year after her incredible AGT audition, with a video of her performance getting a staggering 30 million views on YouTube. Despite her deteriorating health, she had kept fans updated on her battle with photos and videos on social media until her final post on her Instagram feed, where she wrote optimistically about her life's struggles and remained hopeful about the future.
