Lovato rehearsed early in the afternoon, delivering back to back performances of "Cool for the Summer" and "Confident." Lovato was escorted by her longtime boyfriend, actor Wilmer Valderramma, who posed with members of the New York City Police Department as the famed New Year's Eve Waterford Crystal Ball was raised high above Times Square.
Puth and Khalifa rehearsed "See You Again" shortly before broadcast, and Puth seemed unfazed by the cold. He removed his parka after the first performance, and was all smiles before playing the first notes of the song, which the duo performed amidst a blast of smoke and confetti. Wiz was in good spirits, doing a little shuffle on stage as Taylor Swift's "Bad Blood" filled the air.
The broadcast has something for everyone, according co-host Jenny McCarthy.
“If you’re a country fan, Times Square is the place to be because we’ve got Carrie Underwood and Luke Bryan performing,” McCarthy told Billboard.
