One of the acts Howard Stern got to critique in his highly-anticipated debut as a judge on 'America's Got Talent' last night was the father/daughter team of Jorge and Alexa Narvaez, who charmed even the hard-to-please shock jock with their cover of 'Home' by Edward Sharpe and the Magnetic Zeros.

The Narvaez duo had earned more than 20 million views of their performance of 'Home' on YouTube before taking the stage in L.A. to impress the 'AGT' panel. Alexa won over the crowd with her cheerful personality. The 7-year-old said she's been singing since "the day I was one years old."

She admitted before the song, "I'm scared. This is a lot of people. It's like 609!" The youngster was on-key and adorable during the cute duet. Afterwards, when Stern said, "Jorge, I wish you were my dad," Alexa asked the radio host, "What happened to your daddy?" Stern said, "You don't want to know! You know, my dad never wanted to play guitar with me." Alexa replied, "Aw, I hope you don't cry!"

"This has been the most touching moment on the show so far for me," Stern said, joining Howie Mandel and Sharon Osbourne in agreeing to send the duo to the next round of judging in Las Vegas.

We'll find out in the coming weeks whether Jorge and Alexa have more up their sleeves beyond 'Home,' but their duet was undoubtedly one of the highlights of 'America's Got Talent' last night.
