Jennifer Lopez kicked-off the American Music Awards on Sunday with a dance medley of a few of the biggest hits this year.

First, Lopez threw it back to 1999 with a slowed-down version of her song “Waiting for Tonight” before launching into a multi-dance-style performance of “Uptown Funk,” “Anaconda,” “7/11,” “Feelin’ Myself,” “Thinking Out Loud” and “Bad Blood,” among others.

Other highlights included a “Star Wars” soundtrack tribute by a cappella group Pentatonix, a colorful, psychedelic performance of “Adventure of a Lifetime” by Coldplay and a duet of “You Oughta Know” from Alanis Morissette and Demi Lovato.

Celine Dion also gave a moving tribute to the victims of the Paris attacks, singing a cover of Edith Piaf’s “Hymne à l’amour” as various audience members could be seen crying.

Justin Bieber closed out the show by performing his latest three hit singles: an acoustic version of “What Do You Mean,” his hit dance single “Where Are Ü Now” and a dripping wet rendition of “Sorry.”

Among the top winners of the night were One Direction for Artist of the Year, Taylor Swift’s “Blank Space” for Song of the Year, Nicki Minaj for Favorite Artist Hip-Hop/Rap, Fall out Boy for Favorite Artist Alternative Rock, Luke Bryan for Favorite Male Artist Country and Carrie Underwood for Favorite Female Artist Country.
