Grace VanderWaal, a 12-year-old singer-songwriter with a ukulele and Anna Wintour's haircut, was crowned the winner of Season 11 of America's Got Talent Wednesday night.

The Suffern, NY, native wowed the judges — Howie Mandel used his Golden Buzzer at her audition early in the season — and the voting public with her precocious talent. During the finale, she performed two original songs, "I Don't Know My Name" and "Clay." She was awarded a grand prize of $1 million.

The mentalist duo the Clairvoyants came in second.
