'American Idol' Season 21 winner? 5 facts about Iam Tongi

In a shocking turn of events, 18-year-old high school senior Iam Tongi was crowned the Season 21 winner of "American Idol" on Sunday night.

During the live finale, the remaining three contestants − Megan Danielle, Colin Stough and Iam Tongi − performed two songs: one by guest mentor Keith Urban and another in tribute to their hometowns. Then, host Ryan Seacrest revealed which contestants made the Top 2, surprising fans nationwide.
