Karlie Hay of Texas crowned her successor, Sophia Dominguez-Heithoff of Missouri at the end of the event.
The pageant was hosted by celebrity personal trainer and author Heidi Powell and E!
correspondent Erin Lim, while Mexican singer Jorge Blanco performed.
It was the first time the pageant was held in Arizona and the first to broadcast in high dynamic range (HDR) color, virtual reality and on PlayStation consoles.
Prior to the final competition, the delegates compete in the preliminary competition, which involves private interviews with the judges and a presentation show where they compete in athletic wear and evening gown.
