Everybody said yes when Travis Pratt, 32, auditioned for NBC's "America's Got Talent" Tuesday night. "Everyone" meaning the show's four judges, after Pratt stunned them with opera, and his girlfriend, after Pratt got down on one knee on the stage and asked her to marry him.

Pratt's girlfriend of five years, who wasn't named on the show, was a part of the audition from the moment he stepped onstage, as he immediately gave her credit for encouraging him to try out. Then he launched into a stunning opera performance, complete with soaring falsetto and risky high notes. Three seconds into his song, the audience had leapt to its feet applauding.

"Were you lip-syncing?" demanded judge Howie Mandel as Pratt finished. "That was you hitting those notes?"

"All day," answered Pratt.

"You are a freak, but I mean it in like, a good way," said Howard Stern.

Mandel then insisted that Pratt's girlfriend come up on stage. "You have a very special lady," he told Pratt.

The singer agreed, and then added, "And I have something to say to her," before kneeling with a ring at the ready to ask, "Will you marry me?"

She said yes, and so did the judges, making for a most operatic night.
