It's the most wonderful time of the year, where musicians gather 'round the yule log that is the Jingle Ball stage at The Forum.

The annual concert hosted by the LA-based radio station KIIS-FM has been bringing people together since its inception in 2000. Each year, the concert ho-ho-hosts a variety of artists, and this year, welcomed Katy Perry, BTS, Billie Eilish, Sam Smith, Camila Cabello, Halsey, French Montana, Lizzo and Normani.

Check out highlights from some of the fierce and festive performances below, and if you were in attendance, make sure to fill out some of the other setlists!

Katy Perry

Katy Perry lit up the stage like a firework – I mean Christmas tree – with an eight-song set, consisting of a good mix of classics and new songs alike!

She kicked things off on a festive note, with a rendition of "Cozy Little Christmas" before getting into favorites like "Teenage Dream," "I Kissed a Girl" and "Dark Horse."

She also played new songs "Haryleys In Hawaii" and "Never Really Over," and closed out with the ever-anthemic "Roar" and "Firework."

Check out her third-ever performance of "Never Really Over!"

Normani

Normani sleigh-ed her performance with a four-song set, warming up the crowd with "Motivation" before getting into other hits like "Checklist," "Waves" and "Love Lies."

Check out her full performance below!

Halsey

Halsey may be "Bad at Love," but it was certainly love at frost sight watching her perform at Jingle Ball!

She performed "Graveyard" and "Without Me" from her forthcoming third album, Manic, as well as her beloved Benny Blanco and Khalid collab "Eastside."

Watch her perform "Graveyard" below ... and can we talk about those pants?! 😍

BTS

The greatest gift of all? A performance by BTS. The boyband played songs "MIC Drop" and "Make It Right" before Halsey joined onstage for a rendition of "Boy With Luv." (We were really hoping to catch a first live listen to the new Halsey/Suga track "Suga's Interlude," but we'll wait).

Billie Eilish

She may be a "bad guy," but there was no sign of a "resting Grinch face" on Friday night when Billie Eilish took the stage!

She played five songs off her hit album When We All Fall Asleep, Where Do We Go?, including "you should see me in a crown," "all the good girls go to hell" and "bury a friend."

Check out her performance of "bad guy" below!
