Jorge And Alexa Narvaez, YouTube Sensations, Sing 'Home' On 'America's Got Talent' (VIDEO)

Jorge and Alexa Narvaez are back in the spotlight, but this time the father-daughter duo has taken their talents, as first displayed in a viral YouTube performance, to "America's Got Talent."

The father-daughter pair, who captured the hearts of millions of Internet users since launching their own YouTube channel, began their journey to a $1 million prize by singing "Home" on the Los Angeles stage.

Seven-year-old Alexa's spunky attitude made their appearance on the NBC show all the more memorable.

"What happened to your dad?" she asked new judge Howard Stern after he complimented Jorge's performance.

"You don't wanna know," Stern said, and the crowd erupted in laughter.

This emotional performance may have appealed to the radio talk show host, but was their duet good enough to convince judges Howie Mandel and Sharon Osborne to move them further into the competition?
