Travis Pratt 'America's Got Talent' Proposal [VIDEO]: Opera Singer Wows Judges with 'Outrageous' Voice, Asks for Girlfriend's Hand in Marriage Onstage

On Tuesday evening's episode of "America's Got Talent" (June 11), Opera singer Travis Pratt wowed the judges with his "outrageous" singing voice. He also won Howie Mandel's praise after calling his girlfriend up onstage, getting down on one knee, and proposing. Watch the adorable audition clip below.

The Georgia native reveals that his girlfriend encouraged him to attend auditions for "America's Got Talent." And good thing she did - the judges loved him! Pratt totally shocked the panel with his killer vocals and unique song selection... he sang one of his girlfriend's favorite tune and dedicated the performance to her. In the end, three judges (excluding Mel B) stood for a standing ovation... including several members of the audience. Howard Stern called Pratt a "freak" (in a good way), and Mandel couldn't believe that he wasn't lip-syncing. Heidi Klum deemed Pratt a "superstar." Check it out:

Mandel eventually pulled Pratt's sweetheart of five years up onstage... and that's when things REALLY got adorable. Pratt got down on one knee and asked for her hand in marriage as the crowd exploded in applause. Of course she said yes, and of course host Nick Cannon shed some (fake) tears of joy. The judges gave Pratt another standing ovation - Mel B yells "put a ring on it!' while Mandel proclaims, “Thank you for sharing this moment with the nation."

How cute!
