VIDEO: 12-Year-Old Ventriloquist Stuns AMERICA'S GOT TALENT Judges

A 12-year-old who uses ventriloquism to overcome her shyness stunned the crowd with a surprising singing act on last week's AMERICA'S GOT TALENT. Below, watch as she stuns the audience and the judges with a performance of the George Gershwin classic 'Summertime' and gets a Golden Buzzer from Mel B!

"Summertime" was composed in 1934 by George Gershwin for the 1935 opera PORGY AND BESS. The lyrics are by DuBose Heyward, the author of the novel Porgy on which the opera was based.

On the heels of the most viewed season in five years, the 12th season of "America's Got Talent" is back with creator and judge Simon Cowell, Mel B, Heidi Klum and Howie Mandel. Supermodel, entrepreneur and CEO, Tyra Banks, joins the team as host and the series returns to Los Angeles this summer with live shows from the famed Dolby Theatre.

With the search open to acts of all ages and talents, "America's Got Talent" has brought the variety format back to the forefront of American culture by showcasing unique performers from across the country. The series is a true celebration of creativity and talent, featuring a colorful array of singers, dancers, comedians, contortionists, impressionists, jugglers, magicians, ventriloquists and hopeful stars, all vying to win America's hearts and the $1 million prize.

Last summer, "America's Got Talent" remained the #1 summer show and had the highest-rated season in five years, with a season average of 13.5 million viewers and more than 1 billion video views across its far-reaching social media handles. The exciting finale came down to teen singing sensation Grace VanderWaal and spell-binding illusionist duo The Clairvoyants. The charming VanderWaal triumphed and won America's hearts.

VanderWaal went on to release her first EP, titled "Perfectly Imperfect," which became the highest-selling EP of 2016, demonstrating the power of "AGT" to create an instant star. Also, her "Got Talent" audition video was one of the top trending videos of the year and currently has over 135 million views.

Past "AGT" highlights include first-ever magician winner in 2014, Mat Franco, who went on to headline the "America's Got Talent Live" stage show as well as the "Magic Reinvented Nightly" stage show - both held in Las Vegas. Another fan favorite was the season-seven winner Olate Dogs in 2012. Led by Richard Olate and his son Nicholas, this high-energy, fast-paced dog act was an audience favorite filled with unbelievable pet tricks.
