Travis Pratt had himself a pretty good audition on last night's episode of America's Got Talent: First the Georgia singer stunned the crowd and judges with a performance of operatic proportions that showcased his hair-raising falsetto. Then he got engaged. After his audition, Pratt said the song was one he usually just sang around the house, and credited his girlfriend for pushing him to take the stage. "Don't you think everyone should hear this?" Pratt's girlfriend said after being brought up onstage. To top it all off, Pratt proceeded to get down on one knee asked her to marry him. Of course, she said yes.
