"Happier Than Ever" is the title track from Eilish’s sophomore album, which debuted at No. 1 on the Billboard 200.
The duo will work with teams assembled by coaches John Legend, Michael Bublé, Kelsea Ballerini & Adam Levine.
"You just sing the living crap out of everything you sing," said Adam Levine.
"You got great taste in music, man," Levine jokes, as Divign goes head-to-head with Kaiya Hamilton performing Alessia Cara's "Here."
"It was a very unlikable thing in the industry," the singer said of the competition show she won.
Conor James and Tinika Wyatt lit up the stage with a duet of the Bee Gees’ Billboard chart-topper “How Deep Is Your Love".
Team Kelsea’s Alanna Lynise and Brook Wood impressed with their performance of "Angels Like You".
“I want to drink bourbon with you, and I don't even drink bourbon,” Kelsea Ballerini told Fran Posla.
Michael Bublé also had to turn around to find out more about the 24-year-old Atlanta singer.
The 29-year-old delivered an emotional performance of Ed Sheeran’s "The A Team."
