More than 20 years ago, New York's Z100, the most listened to pop radio station in the country, introduced Jingle Ball—a holiday concert with the year's top artists performing their #1 hits. The show quickly became the most anticipated holiday tradition with tickets selling out in minutes. Jingle Ball has since grown into a globally-recognized phenomenon-now a sold-out multi-city national tour-and a must-stop appearance for the world's biggest artists to get face-to-face with thousands of their most passionate fans.

The network special, airing Dec. 21 (8-10 p.m. ET/PT), will feature footage from all iHeartRadio Jingle Ball tour stops. The special will be available on demand and on Hulu the following day.

Performers include:

OLIVIA RODRIGO
