The 7 Most Memorable Moments from Jingle Ball 2016

After Fifth Harmony kicked off the show with hits like "Work from Home" and "Worth It," Cabello reappeared to perform her new single "Bad Things" with Houston rapper Machine Gun Kelly.

Joe Jonas's band DNCE got the crowd on their feet when they threw it back to the '90s with a cover the Spice Girls' seminal hit "Wannabe."

Per Jingle Ball tradition, a group of artists, including Hailee Steinfeld, Fifth Harmony, Daya, DNCE, Charlie Puth, Cole Whittle, Jake Miller, Sabrina Carpenter, Rita Ora, and Tinashe, took to the stage to belt out lyrics from the classic Christmas song "Santa Claus Is Comin' to Town," along with a fleet of Santas.

The pint-sized singer performed songs like "Side to Side" and "Dangerous Woman" wearing earmuffs and furry mittens. 

The DJ duo mixed up their set with covers of Red Hot Chili Peppers's "Under the Bridge," Coldplay's "Yellow," and the Rocky theme song.

Beliebers and Sex and the City fangirls alike erupted in screams when SJP graced the stage to introduce the pop star as "the one, the only ... Justin Bieber!"

After a strong open with upbeat hits like "Where Are Ü Now," "Boyfriend," and "Company," Bieber grabbed his guitar and sang acoustic versions of "Cold Water" and "Love Yourself."
