The Weeknd’s Flames, 1D’s Goodbye, Selena’s Sweet Talk & More Jingle Ball Moments

Check out all the highlights from L.A.'s hyped-up Jingle Ball.

LOS ANGELES -- Downtown L.A. was lit last night (Dec. 5) when KIIS FM's Jingle Ball rolled into town, toting a killer lineup of pop's biggest names and buzziest newcomers.

The genius of Jingle Ball lies in its breakneck format: Have each artist perform only four to six songs, focusing on their biggest hits. It's like getting 12 best-of performances in a single night, which is great for both the artists' energy levels and the fans' attention spans.

Without skipping a beat, the lights dimmed inside the Staples Center at 7:30 p.m. and the opening chords of 5 Seconds of Summer's "She Looks So Perfect" warned the crowd to get the eff up out of their seats. And from there, it was a nonstop party filled with raucous music, surprise new faces and a whole lot of festive fun. Check out the best moments from each performer:

  • 5 Seconds of Summer kicked things off with raging energy.

    Standout moment: Playing their new single “Jet Black Heart” (and thus proving Michael Clifford may be the band’s not-so-secret weapon).

  • Ellie Goulding’s ethereal vocals made the Staples Center feel like heaven.

    Standout moment: Filling her setlist with upbeat, fun songs — especially “Love Me Like You Do,” which inspired a chill-inducing crowd singalong.

  • Charlie Puth was a piano man who sang us a song and had us feeling all right.

    Standout moment: His heartfelt intro to “See You Again”: “This song changed my life. I wrote it for Paul Walker and my best friend.”

  • Hailee Steinfeld made us all love ourselves.

    Standout moment: The joyous cheekiness of “You’re such a diiii…fficult little devil.” That song is 10 million times more fun in an arena setting.

  • Conrad Sewell proved why he’s an artist to keep an eye on.

    Standout moment: Pretty much his entire set — because those who weren’t familiar with him were left with their jaws on the floor, and those who were already fans were going “I TOLD YOU!”

  • Tove Lo proved pants are always optional.

    Standout moment: The girl’s style is always on point, what can we say?! But the real highlight was “Talking Body,” which had everyone in the arena feeling frisky and fine.

  • Zedd supplied the mid-show dance break.

    Standout moment: Turning the venue into the most colorful dance club you’ve ever seen.

  • One Direction gave their absolute all to their last U.S. show of 2015.

    Standout moment: When frontman Joe Jonas ran offstage and immersed himself into the crowd, surprising everyone (even, by the looks of it, the security guards). Also, Cole Whittle’s short shorts and general hyper stage presence.

  • Selena Gomez was equal parts sultry and sweet.

    Standout moment: When she closed out her set with “Kill Em With Kindness,” prefacing it with a wish that the world becomes a more peaceful place, in light of recent events.

  • And The Weeknd was hype as hell.
