"America's Got Talent" is back! And though host Nick Cannon and judges Heidi Klum, Howard Stern, Howie Mandel and Mel B are all returning, Season 9 has some big changes. These include the addition of the Golden Buzzer, an automatic save each judge can use only once, and now acts can submit their auditions online to the "Today" show, with one act being voted to the live shows.

May 27's much anticipated premiere featured a 9-year-old piano prodigy; the judges getting pranked and the shocking first appearance of the Golden Buzzer.
