Pint-sized powerhouse singer Grace VanderWaal, just 12 years old, was named winner of “America’s Got Talent” on Wednesday night. She collected the $1 million prize and will headline a Las Vegas show.

The ukulele-playing pre-teen from Suffern, New York — described by Simon Cowell as “the next Taylor Swift” — was a favorite going into the finale and wound up beating magician Jon Dorenbos and The Clairvoyants, a mentalist duo.

“We’re all going to remember when we saw Grace sing for the first time,” said Cowell.

Less than one percent of the vote separated the top three, noted turban-wearing host Nick Cannon.

“You are a shooting star!” judge Howie Mandel told the sobbing young winner as tons of confetti dropped down on her.

“The show has changed my life forever,” said VanderWaal before winning. She was crying too hard to talk after she won.
