Cancer Survivor Calysta Bevier And Rachel Platten Duet 'Fight Song'

(Radio.com) Calysta Bevier, a sixteen-year-old survivor of stage-three ovarian cancer, wowed audiences with her performance of Rachel Platten's "Fight Song," Tuesday night on America's Got Talent.

Judge Simon Cowell hit his golden buzzer, which automatically sends Calysta to next round. Bevier may have already been familiar to some viewers who remember her duet with Platten on Ellen.

Ellen invited Calysta onto her show after a YouTube video of the teen performing the track went viral, and surprised her by bringing out Platten for a duet.
