Watch 'America's Got Talent' Opera Singer Laura Bretan Perform with Il Volo


America's Got Talent opera singer Laura Bretan, 14, had the opportunity of a lifetime when she was paired with Il Volo on the Wednesday night season finale at the Dolby Theatre in Hollywood.

Bretan, who previously won Romania's Got Talent, joined the handsome Italian "popera" trio -- baritone Gianluca Ginoble and tenors Ignazio Boschetto and Piero Barone -- for a beautiful rendition of "Nessun Dorma."

The performance also included contortionist Sofie Dossi and juggler Viktor Kee, adding to the visuals.

This isn't the first time Il Volo has guested on a reality competition: The group previously performed on American Idol during Season 10.

After the two-hour finale, 12-year-old singer/ukulele player Grace VanderWaal was crowned the winner.
