Jackie Evancho makes splash on TV talent show (video)

Watch out, Susan Boyle. Here comes Jackie.

A 10-year-old Pennsylvania girl who was chosen by YouTube viewers to compete on NBC's America's Got Talent stunned the judges and audience Tuesday night with her big voice.

Jackie Evancho, of Pine Township, sang Giacomo Puccini's aria "O Mio Babbino Caro" and received praise from the judges and overwhelming applause from the audience.

The tiny blonde wore a pink ruffled dress and a big smile. After the performance, Jackie said she was so happy she wanted to cry.

Jackie was one of 12 acts who performed on the show Tuesday night. Four of those performers will join 20 other semifinalists who are competing for $1 million and a contract to perform in Las Vegas.
