Jackie says she realizes her voice is a gift. "I say three prayers every night to make sure that God knows I thank him so much," she says.
Jackie says she wasn't nervous during the competition, performing in front of millions every week. "The adrenaline helped me to realize that you're on a big stage and you just have to deal with it," she says.
As she continues to tour with other America's Got Talent contestants, Jackie says she still doesn't get nervous when she steps up to a mic. "It's more like excitement and joy," she says.
