It's officially fall, so you know what that means - Christmas is right around the corner! Leading up to 2015's holiday season, on Monday (Oct. 5), iHeartRadio announced the initial lineup for this year's Los Angeles KIIS FM Jingle Ball, featuring One Direction, Selena Gomez, 5 Seconds of Summer and more.

As E! Online reports, Ryan Seacrest unveiled the acts set to take the Jingle Ball 2015 stage on his syndicated radio show Monday morning, and the event is set to be somewhat of a who's-who in pop music, including plenty of acts who will be releasing new albums this fall.

In addition to One Direction, Gomez and 5SOS, The Weeknd, Ellie Goulding, Shawn Mendes, Tove Lo, Charlie Puth, Zedd, Hailee Steinfeld, Conrad Sewell and Joe Jonas' new band DNCE will all perform at the L.A. Jingle Ball stop.

The Los Angeles Jingle Ball will take place on Dec. 4, and tickets will go on sale for the general public on Oct. 12. Acts for the other 2015 Jingle Balls have yet to be announced, though iHeartRadio has announced that Nick Jonas will be performing at at least one stop on the annual tour.
