AGT fan favorite Jane "Nightbirde" Marczewski made headlines last year when she had to drop out in the middle of last season after the breast cancer she survived in 2017 returned. TMZ reports Nightbirde died Sunday "months of receiving treatment for the disease ... which had spread to her lungs, spine and liver." AGT host Terry Crews paid tribute to Nightbirde on Instagram: "We are saddened to learn about @_nightbirde's Passing. Our Condolences goes to her Closest Family & Friends in such of This difficult time. We Love you, Nightbirde."
