Bieber opened the finale performance by singing a stripped-down version of his track "What Do You Mean?" with an acoustic guitarist accompanying him. Next, he transitioned into his song "Where Are Ü Now," joining a group of male dancers for a dance breakdown.

Lastly, he performed "Sorry" from under a huge waterfall, where he was joined by a group of female dancers. At the end of the performance, he took his hat off and ran his hand through his soaked blond hair.
