we're turning back the clock to one of the most jaw-dropping surprises of all time! When 13-year-old Courtney Hadwin walked onto the AGT stage in Season 13, viewers could feel her trepidation.

Season 20 will mark the debut of Mel B and Vergara judging together on the show, but also the first time she will be without Klum on the panel. An 'AGT' season for the history books!
