The show crowned Alisan Porter winner of its 10th season. She becomes the first woman to ever win after being mentored by a female coach, Christina Aguilera.
Porter had impressed the judges from the start, when she auditioned with a cover of Linda Ronstadt's "Blue Bayou."
"You are going to win 'The Voice,'" coach Adam Levine predicted during her audition.
A former child actress, Porter found fame at the age of 10 as the star of the John Hughes movie "Curly Sue." But she also went through a dark period of alcohol addiction
. The married mother of two said she found sobriety eight years ago.
Porter performed "Unlove You" with country star Jennifer Nettles at the show's star-studded finale.
She triumphed over country singer Adam Wakefield, who was declared the runner up. Contestants Hannah Huston and Laith Al-Saadi came in third and fourth place respectively.
Porter closed out Tuesday's show surrounded by her family and singing her new original song, "Down That Road."
