Festival goers in the Village will be entertained by acts such as Panic! At The Disco, Good Charlotte, Jeremih, Alessia Cara and Bryson Tiller.

The iHeartRadio Music Festival, now in its sixth year, has established itself as one of the premier events on the music calendar. Last year, Kanye West, Sam Smith and Coldplay were among the performers.

Fans are also promised "surprise performances" for this year's event and many took to Twitter to express their excitement.

Hooray for the iHeartRadio Music Festival
