The Voice's Billy Gilman Covered Frank Sinatra & We're Crying

Monday night marked Part 1 of The Voice's finale, and the competition is closer than ever between finalists Billy Gilman, Sundance Head, Josh Gallagher, and We McDonald.

What really has everyone talking, however, is former country singer Billy Gilman's Frank Sinatra tribute that floored coach Adam Levine. Gilman himself was fighting tears after his emotional rendition of "My Way" in honor of what would have been the classic singer's 101st birthday if he were still alive.

"Everything this guy has been through was just poured out from his heart on that stage. How do you not feel like you just won The Voice just now?'" said Levine to the performer, once criticized for the lack of emotion in his performances.

The second part of The Voice season 11 finale airs tonight, Tuesday, December 13 at 8 p.m. But first be sure to watch the cover everyone's talking about below:
