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.
When it comes to future collaborators, Jackie's already thought about who would be on her dream team. "There are several, actually. There's Josh Groban, Charlotte Church, Andrea Bocelli," she says. "And this lady is not really my type of singing, but it's Lady Gaga."
